▼ Os manguezais estÃo distribuÃdos do extremo norte do Brasil atÃ Laguna, regiÃo costeira sul do paÃs, ocorrendo em estuÃrios, lagoas litorÃneas e canais de marÃ. No estado do CearÃ (02Â46 S), nordeste brasileiro, o clima semi-Ãrido apresenta caracterÃsticas que condicionam o crescimento dos bosques de mangue como a sazonalidade das chuvas e a alta incidÃncia de radiaÃÃo solar. As caracterÃsticas climÃticas favoreceram a escolha pela regiÃo para implementaÃÃo da industria salineira no sÃculo passado, como no caso do complexo estuarino do rio CearÃ, localizado na divisa costeira entre os municÃpios de Fortaleza e Caucaia. O presente estudo descreve e analisa a evoluÃÃo espaÃo-temporal do manguezal do rio CearÃ (Fortaleza-CE), com foco na colonizaÃÃo da vegetaÃÃo tÃpica de mangue em Ãreas de salinas abandonadas. O estudo da paisagem foi realizado atravÃs de tÃcnicas de sensoriamento remoto, uso de fotografias Ãreas e imagens de satÃlites, alÃm de visitas de campo, sendo produzidos e analisados mapas temÃticos dos anos de 1968, 1997 e 2009, estimando-se as Ãreas de manguezais e de salinas para cada ano. Para o ano de 2009, foram estimados 1006,6 ha de manguezais, 165% a mais do que em 1968, apresentando sua maior taxa de crescimento por dÃcada entre 1997 e 2009, de 133,25ha/10anos. No perÃodo estudado de 41 anos uma Ãrea de 395 ha de salinas abandonadas foi colonizada naturalmente por bosques de mangue. Uma descriÃÃo mais detalhada da estrutura desses bosques foi realizada atravÃs do estudo fitossociolÃgico na salina Margarida. Na regiÃo mais prÃxima Ã margem do rio foi encontrado um bosque em um estÃgio de desenvolvimento avanÃado, com dominÃncia de Rhizophora mangle e presenÃa de Avicennia spp., altura mÃdia do bosque 10m, DAP mÃdio 14,06 cm e densidade de 1333,33trocos/ha. Em direÃÃo ao continente, evidenciou-se um bosque em processo de colonizaÃÃo inicial na salina, sendo a espÃcie pioneira Laguncularia racemosa associada Ã outras espÃcies vegetais, Portulaca oleracea (beldroega) e a Batis marÃtima (brejo do mangue). Apesar do crescimento quantitativo dos bosques de mangue foram evidenciados diversos impactos ambientais, que acumulados, ocasionaram desequilÃbrio ambiental e perda qualitativa nos benefÃcios proporcionados pelo manguezal do rio CearÃ. Para evidenciar os bens e serviÃos do ecossistema foi realizada uma anÃlise sistÃmica dos fluxos de matÃria e energia que compÃe o complexo estuarino do rio CearÃ. A relaÃÃo dos fluxos com as atividades humanas estabelecidas no ambiente evidenciaram principalmente uma interferÃncia dos impactos ambientais nos serviÃos ambientais relacionados com os fluxos litorÃneos (construÃÃo de espigÃes e dÃficit de sedimentos na costa), fluxos fluvio-marinhos (salinizaÃÃo do estuÃrio e contaminaÃÃo das Ãguas) e os fluxos de sedimentos e gravitacionais (abandono das salinas, impermeabilizaÃÃo do solo e ocupaÃÃo intensa nas Ãreas de dunas). A partir das evidÃncias da recuperaÃÃo do manguezal em Ãreas de salinas abandonadas no rio CearÃ, pÃe-se em discussÃo as definiÃÃes da resoluÃÃo… Advisors/Committee Members: AntÃnio Jeovah de Andrade Meireles, Renato de Almeida, Adryane Gorayeb Nogueira Caetano.

▼ Os recentes avanços em cosmologia observacional indicam que o universo esteja passando por uma fase de expansão acelerada. A determinação do mecanismo responsável pela aceleração cósmica constitui um dos problemas mais intrigantes na ciência hoje. Entre os diversos candidatos a mecanismo de aceleração, a explicação mais simples e econômica é assumir a existência de uma constante cosmológica associada à energia do vácuo. Contudo, essa interpretação leva a importantes problemas conceituais associados à natureza dessa componente. Nesta tese, investigamos a dinâmica de diferentes mecanismos de aceleração cósmica, comparando suas previsões com diversos testes observacionais. Em particular, demos ênfase aos cenários baseados na criação de matéria escura fria (CCDM), nos quais a presente aceleração do universo é produzida sem a presença de um fluido exótico, como consequência do processo de produção de partículas de matéria escura gravitacionalmente induzido. Inicialmente, propusemos um modelo no qual o mecanismo de criação de partículas é capaz de gerar uma cosmologia dinamicamente degenerada com o modelo padrão, CDM. Discutimos no chamado modelo de Lima, Jesus & Oliveira (LJO) a dinâmica cosmológica com criação de matéria escura fria e com pressão. Através de um teste estatístico de \χ², mostramos que o modelo fornece ótimo ajuste aos dados de supernovas tipo Ia (SNe Ia). Posteriormente, estudamos a evolução de pequenas perturbações de densidade em um fundo homogêneo para modelos tipo CCDM, através do formalismo Neo-Newtoniano. Restringindo-nos ao modelo LJO, comparamos as previsões obtidas nesse contexto com as proveniente do modelo CDM. Mostramos que o modelo é capaz de fornecer excelente ajuste aos dados observacionais de medidas da taxa de crescimento linear, para o caso plano e com velocidade efetiva do som c²_=-1. Ainda dentro do cenário CCDM, investigamos uma segunda proposta original, com capacidade de ajuste às observações similar aos modelos CDM e LJO com mesmo número de parâmetros livres, porém com dinâmica não degenerada com estes. Derivamos a dinâmica cosmológica do modelo e discutimos a sua viabilidade através da análise estatística de medidas de SNe Ia e do parâmetro de Hubble em diferentes redshifts H(z). Finalmente, discutimos a dinâmica de um modelo com decaimento do vácuo ((t)CDM) e sua descrição em campos escalares. Assumindo como forma d o termo de vácuo uma série de potências truncada do parâmetro de Hubble, derivamos as equações dinâmicas básicas e as previsões cosmológicas do modelo. Mostramos que, quando a transferência de energia entre as componentes dos setor escuro se dá através da criação de partículas, modelos CCDM e (t)CDM podem compartilhar a mesma dinâmica e termodinâmica, dentro de certas condições. Adicionalmente, mostramos que o modelo é capaz de prover um bom ajuste às medidas de SNe Ia e da chamada razão CMB/BAO. Obtivemos ainda uma descrição do modelo (t)CDM por um campo escalar, estendendo a validade do modelo para outros espaços-tempos e outras teorias… Advisors/Committee Members: Lima, José Ademir Sales de.

▼ Dark matter, a non-luminous, non-baryonic matter, is thought to constitute 23 % of the matter-energy components in the universe today. Except for its gravitational effects, the existence of dark matter has never been confirmed by any other means and its nature remains unknown. If a hypothetical Weakly Interacting Massive Particle (WIMP) were in thermal equilibrium in the early universe, it could have a relic abundance close to that of dark matter today, which provides a promising particle candidate of dark matter. Minimal Super-Symmetric extensions to the standard model predicts a stable particle with mass in the range 10 GeV/c 2 to 1000 GeV/c 2 , and spin-independent cross-section with ordinary matter nucleon σ x ∠ 1 × 10 -43 cm 2 . The XENON100 experiment deploys a Dual Phase Liquid Xenon Time Projection Chamber (LXeTPC) of 62 kg liquid xenon as its sensitive volume, to detect scintillation ( S1 ) and ionization ( S2 ) signals from WIMP dark matter particles directly scattering off xenon nuclei. The detector is located underground at Laboratori Nazionali del Gran Sasso (LNGS) in central Italy. 1.4 km of rock (3.7 km water equivalent) reduces the cosmic muon background by a factor of 10 6 . The event-by-event 3D positioning capability of TPC allows volume fiducialization. With the self-shielding power of liquid xenon, as well as a 99 kg liquid xenon active veto, the electromagnetic radiation background is greatly suppressed. By utilizing the difference of ( S2/S1 ) between electronic recoil and nuclear recoil, the expected WIMP signature, a small nuclear recoil energy deposition, could be discriminated from electronic recoil background with high efficiency. XENON100 achieved the lowest background rate (∠ 2.2 × 10 -2 events/kg/day/keV) in the dark matter search region (∠ 40 keV) among all direct dark matter detectors. With 11.2 days of data, XENON100 already sets the world's best spin-independent WIMP-nucleon cross-section limit of 2.7 × 10 -44 cm 2 at WIMP mass 50 GeV/c 2 . With 100.9 days of data, XENON100 excludes WIMP-nucleon cross-section above 7.0 × 10 -45 cm 2 for a WIMP mass of 50 GeV/c 2 at 90% confidence level.

▼ This thesis explores two dominant frontiers of theoretical physics, high energy colliders and hidden sectors. The Large Hadron Collider (LHC) is just starting to reach its maximum operational capabilities. However, already with the current data, large classes of models are being put under significant pressure. It is crucial to understand whether the (thus far) null results are a consequence of a lack of solution to the hierarchy problem around the weak scale or requires expanding the search strategy employed at the LHC. It is the duty of the current generation of physicists to design new searches to ensure that no stone is left unturned. To this end, we study the sensitivity of the LHC to the couplings in the Standard Model top sector. We find it can significantly improve the measurements on Zt R t R coupling by a novel search strategy, making use of an implied unitarity violation in such models. Analogously, we show that other couplings in the top sector can also be measured with the same technique. Furthermore, we critically analyze a set of anomalies in the LHC data and how they may appear from consistent UV completions. We also propose a technique to measure lifetimes of new colored particles with non-trivial spin. While the high energy frontier will continue to take data, it is likely the only collider of its kind for the next couple decades. On the other hand, low-energy experiments have a promising future with many new proposed experiments to probe the existence of particles well below the weak scale but with small couplings to the Standard Model. In this work we survey the different possibilities, focusingon the constraints as well as possible new hidden sector dynamics. In particular, we show that vector portals which couple to an anomalous current, e.g., baryon number, are significantly constrained from flavor changing meson decays and rare Z decays. Furthermore, we present a new mechanism for dark matter freezeout which depletes the dark sector through an out-of-equilibrium decay into the Standard Model.

▼ The field of theoretical cosmology consists of numerous, inter-related branches, whose ambitious goal is to uncover the history of the universe from its beginning to its future. Achieving this, no doubt, requires a deep understanding of many areas of physics. In this thesis I touch upon a few of these areas in which I worked during my PhD studies. Chapter~(\ref{ch:accretion}) describes our work in finding the accretion and merger history of dark matter halos. Dark matter halos are the collapsed dark matter structures in the late time evolution of the universe, whose existence is vital for the formation of galaxies in the Universe as they act as the potential wells where normal matter (collectively called Baryons) can accumulate, cool, and form stars. It is then no surprise that the properties of galaxies depends on the properties of the dark matter halo in which it resides, including its merger history, i.e. the number of times it merged with other halos. Even though these merger rates can be calculated theoretically for infinitesimal time steps, in order to find the merger history over an extended period of time one had to use either Monte-Carlo simulations to build up the total rates of merging and accreting from the infinitesimal rates or use N-body simulations. In chapter~(\ref{ch:accretion}) we show how we used random walk formalism to write down an {\it analytical} (integral) equation for the merger history of halos. We have solved this equation numerically and find very good agreement with Monte-Carlo simulations. This work can be used in theories of galaxy formation and evolution. We then switch from the overdense regions of the Universe, halos, to the underdense ones, voids. These structures have not attracted as much attention from cosmologists as their overdense counterparts in probing the cosmological models. We show here that the shapes of voids as a probe can be of use for future surveys to pin down the equation of state of the dark energy, i.e. the ratio of its pressure to its energy density. As first approximation, voids can be considered to be ellipsoids whose axis ratio evolution depends on the cosmological parameters. This, together with the fact that the initial distribution of the axis ratios is known (because the intial density field is Gaussian) can be used to infer the equation of state of the dark energy statistically from the observation of voids at different redshifts and with different sizes. The standard method of Fisher matrices is then used to forecast how well a future survey can measure the equation of state. We find promising results with constraints coming from void ellipticity measurements comparable to those of other standard methods. Chapter~(\ref{ch:H2}) goes farther back in the history of the Universe. During the {\it recombination} era, when the Universe was around a thousandth of its present size, it became cool enough that free electrons got captured by free protons to make hydrogen atoms. Consequently, the Thompson scattering of photons off of free… Advisors/Committee Members: Wandelt, Benjamin D. (advisor), Fields, Brian D. (Committee Chair), Wandelt, Benjamin D.

▼ An abundance of astrophysical and cosmological evidence indicates the existence of a non-luminous, non-baryonic form of matter, called dark matter, that is approximately a quarter of all energy in the universe. One promising candidate for dark matter is the Weakly Interacting Massive Particle (WIMP) which interacts with baryonic matter at most on the scale of the weak force. The Cryogenic Dark Matter Search (CDMS) experiment aims to detect the nuclear recoils induced by the elastic scattering of WIMPs off of germanium nuclei. This is a rare signal and difficult to detect, especially the low-energy recoils that are produced by low-mass dark matter. The CDMS project operated at the Soudan Underground Laboratory from 2003 – 2015, with an upgrade to the SuperCDMS experiment in 2012. The germanium detectors were operated at 50~mK and able to measure both the ionization and athermal phonons produced in a particle interaction. Measuring two signals enables discrimination between electron recoil and nuclear recoil events. An alternative operating mode for the detectors is called the CDMS low ionization threshold experiment (CDMSlite), where a higher bias was applied to the detectors and only the phonon signal analyzed. This method increased sensitivity to low-mass dark matter interactions, but sacrificed discrimination capability. The CDMSlite spectrum had a large contribution from electron recoil background events. From the information gained during the first two CDMSlite Runs, a background model was developed for the third and final CDMSlite Run. Analytical descriptions were identified for those backgrounds that were theoretically known, e.g. tritium β-spectrum, and Geant simulations were used to understand and predict the low-energy spectra from other sources, e.g. Compton scattering. Multiple new models were developed for detectors operated in CDMSlite at Soudan. These include the analytical formula for Compton scattering, and empirical models for surface backgrounds from ²¹⁰Pb contamination of the germanium crystals and detector housing. In order to accurately describe the surface events, a new detector response function was developed that included information about the electric field and energy resolution of the detector. These models were essential to the implementation of a profile likelihood analysis of the CDMSlite Run 3 data, which improved on the sensitivity to dark matter over the Run 2 optimum interval analysis for WIMP masses above 2.5~GeV/c². This demonstrated a successful application of a likelihood analysis to the high-voltage operating mode, and the potential for these analyses in the future SuperCDMS SNOLAB experiment. For the SuperCDMS SNOLAB experiment, the change in background rates from radiogenic neutrons was considered as additional towers of detectors were added, and the feasibility of an active neutron veto as a potential upgrade for large payloads was studied. This veto could be constructed of plastic scintillator with layers of gadolinium resin, and would aid in reducing the nuclear…

The present thesis has purpose the axion research (Dark Matter particles) by Astrophysical observations. The main activity has been established in CAST (Cern Axion Solar Telescope) in Geneva. In this thesis the axion detection prospects are defined in parallel with the detector's data analysis. An engineering approach is also given as main and substantial part (fluid dynamics) for the CAST physics reliability. The research is ongoing to the Dark Energy sector willing to explore the possibility of chameleons (dark energy particles) through radiation pressure.

Η παρούσα εργασία έχει ως σκοπό την αναζήτηση αξιονίων (σωματιδίων Σκοτεινής Ύλης) μέσα από αστροφυσικές παρατηρήσεις. Από τις πρώτες παρατηρήσεις της ταχύτητας περιστροφής αστέρων σε σμήνη Γαλαξιών από τον Zwicky και μετά, έγινε σαφές στην επιστημονική κοινότητα πως η ύπαρξη σκοτεινής ύλης καθώς και η κατανόηση της είναι θεμελιώδους σημασίας για την Κοσμολογία. Το ποσοστό της σκοτεινής ύλης του σύμπαντος (~21%), σε σχέση με το αυτό της ύλης που παρατηρούμε (~4%), καθιστά σαφή την αναγκαιότητα για εντατική έρευνα στο πεδίο αυτό της Φυσικής. Ανάγκη δε, προκύπτει επίσης για την εξερεύνηση της σκοτεινής ενέργειας η οποία αποτελεί το υπόλοιπο ~75% του Σύμπαντος. Ένα μικρό μέρος της παρούσας έρευνας στο CERN έχει επικεντρωθεί και στην μελέτη Σκοτεινής ενέργειας καθώς, το πείραμα μέσα από το οποίο προσεγγίζεται η αναζήτηση αξιονίων (CAST – CERN Axion Solar Telescope), προσανατολίζεται συγχρόνως στην έρευνα σωματιδίων Σκοτεινής ενέργειας (χαμαιλέοντες) .

▼ The far future provides an excellent laboratory for studying cosmological structures. The eventual dominance of the cosmological constant causes the universe to enter a phase of exponential deSitter expansion during which dark matter halos are allowed to relax without interruptions from mass accretion. Using of suite of N-body simulations evolved to scale factor a = 100 in an LCDM universe, this thesis presents the equilibrium distribution and structure of halos and investigates the importance of mergers in setting the internal halo structure. Using conservation of energy, it is possible to accurately predict the total amount of mass that will ultimately accrete onto a halo. Once this mass is accreted, the halo quickly reaches a state of dynamical equilibrium. Halos in this equilibrium have a greatly simplified radial phase space profile characterized by a single zero-velocity surface that unambiguously defines the halo edge. The radial density profile for such halos is well fit by an NFW profile inside r200, but is steeper at larger radii and better fit by a truncated Hernquist profile. In order to study the importance of hierarchical merging in setting the equilibrium structure, I also present results form LWDM-like simulations with initial power spectra that suppress the early formation of small halos. Using these simulations, I present a modified fit to the mass accretion form of Wechsler et al. (2002) that better characterizes halo growth at all epochs. At the end of the simulations, we recover density profiles and phase space structures that are virtually unchanged between the CDM and WDM cosmologies. The only difference in the global halo properties, a systematic concentration shift, can be characterized in terms of the halo formation epoch. We conclude that mass accretion is not the driving process for setting the equilibrium halo structure. Advisors/Committee Members: Adams, Fred C.

▼ Metal-organic frameworks stand at the frontiers of molecular electronic research because they combine desirable physical properties of organic and inorganic components. They are crystalline porous solids constructed by inorganic nodes coordinated to organic ligands to form 1D, 2D, or 3D structures. They possess unique characteristics such as ultrahigh surface area crystal lattices up to 10000 m2 g-1, and tunable nanoporous sizes ranging from 0.2 to 50 nm. Their unprecedented structural diversity and flexibility beyond solid state materials can lead to unique properties such as tailorable electronic and ionic conductivity which can serve as interesting platforms for a wide range of electronic applications from photonics, sensors, and energy harvesting/storage devices such as photovoltaics, thermoelectrics, supercapacitors to data storage systems like memristors. Despite the significant growth of MOF materials during the past two decades, the fundamental understanding of the resultant electronic and ionic structures at the interface of these hybrid materials are still largely unexplored, and the lack of these properties are the basic requirements for elucidating the physics and chemistry of the devices—The exquisite role of physical electronic properties is crucial for the construction of energy band diagrams of MOF thin films, and is key to achieve further advancement in the development of elaborated devices that require tunability and control over functionality. With this motivation, powerful surface science techniques (e.g. direct and inverse photoemission spectroscopy) have been engaged in this dissertation, which provided useful guidelines to access and study the electronic and chemical structures (e.g. valence and conduction bands, and core electrons) at the internal interface of the individual hybrid constituents of MOF films. This is achieved using a combination of low intensity X-ray photoelectron spectroscopy (LIXPS), ultraviolet photoelectron spectroscopy (UPS), X-ray photoelectron spectroscopy (XPS), and inverse photoelectron spectroscopy (IPES). Furthermore, the density of states obtained from DFT calculations agreed well with the photoemission spectra measurements of the fabricated 2D MOF thin film. Energy level alignment was achieved by judicious selection of various organic ligands in 2D MOF architectures, whereas further incorporation of various pillaring linkers in the 3D MOFs have modified the HOMO and LUMO energy levels as suitable conducting medium for hole or electron transport. The fundamental study delivered in this dissertation gives a unique feedback by tailor-designing the electronic properties of the fabricated 2D to 3D MOF thin films. These crucial properties at the interface offer very important understanding and breakthrough in MOFs as functional and tunable electronic materials.

▼ The energy and charge transfer dynamics for low and hyperthermal energy (10 eV to 2 keV) alkali and noble gas ions impacting noble metals as a function of incident energy, species and scattering geometry has been studied. The experiments were performed in an ultra-high vacuum scattering chamber attached to a low and hyperthermal energy beamline. The energy transfer was measured for K⁺ scattered from a Ag(001) surface along the [110] crystalline direction at a fixed laboratory angle of 90°. It was found that as the incident energy is reduced from 100 to 10 eV, the normalized scattered energy increased. Previous measurements have shown a decrease in the normalized energy as the incident ion energy is reduced due to an attractive image force. Trajectory analysis of the data using a classical scattering simulation revealed that instead of undergoing sequential binary collisions as in previous studies, the ion scatters from two surface atoms simultaneously leading to an increased normalized energy. Additionally, charge transfer measurements have been performed for Na⁺ scattering from Ag(001) along the [110] crystalline direction at a fixed laboratory angle of 70°. It was found that over the range of energies used (10 eV to 2 keV), the neutralization probability of the scattered ions varied from ~30% to ~70% depending on the incident velocity, consistent with resonant charge transfer. A fully quantum mechanical model that treats electrons independently accurately reproduces the observed data. Measurements of electron-hole pair excitations were used to explore the pathways which a solid uses to dissipate the energy imparted by the incident ion beam. Ultrathin film (10 nm) metal-oxide-semiconductor (Au/SiO₂ /n-Si) devices were used to detect the electron-hole pairs for cases when the ion deposited all of its translational energy into the solid. The incident ions were incident at an angle normal to the surface of the device to maximize energy deposition and consequently electron-hole pair production. The rectifying metal-oxide-semiconductor device separates the electrons from the holes, allowing a current associated with electron-hole pair production to be measured. In these experiments a number of ion species (He,⁺ , Li⁺ , Ar⁺ , K⁺ ) were made incident on multiple devices and the incident energy ranged from 100 eV to 2 keV. It was found that electron-hole pair production increased with incident ion velocity consistent with a kinetic electron excitation model where the electrons in the metal are partially confined to the surface.

▼ Photoelectrochemical cells (PECs) are integrated devices that split water using only clean power from the sun, thus producing clean hydrogen fuel with no harmful carbon emissions. The search is on for optimal photoanode materials in PECs. Desired properties include adequate supply, non-toxicity, stability in aqueous solution, ability to split water, and ability to absorb most of the solar spectrum. Titanium dioxide satisfies all but this last criterion; with a bandgap near 3 eV, only the ultraviolet (UV) range of the spectrum may be used. This thesis reports on attempts to improve the visible light activity of TiO₂ by doping with the nonmetals nitrogen and carbon, in order to lower effective bandgap. We have synthesized sets of N- and C-containing TiO₂ via a simple, easily controlled physical vapor deposition (PVD) process known as pulsed laser deposition (PLD). The dopants were introduced by means of a carrier gas: either nitrogen or methane. Atomic concentrations of dopant were found via X-ray photoelectron spectroscopy (XPS) to range from 0-4%. Pure TiO₂ deposits in polycrystalline anatase form at 600°C; nitrogen-doped films were also anatase, while carbon incorporation caused a shift to mixed anatase/rutile character. XPS scans showed changes in electronic structure with increased dopant concentration. In the case of nitrogen, a distinct Ti-N peak appeared, indicating N atoms substituting for O. Carbon-region scans only showed a Ti-C peak at high carbon concentrations. Valence band scans of both C-TiO₂ and N-TiO₂ showed distinct doping states developing just above the valence band. Nitrogen proved more adept at improving visible light activity; with a quantum efficiency peak near 460 nm, and a UV-Visible absorption edge at 510 nm. No such visible light activity resulted from carbon-doping. It is theorized that the carbon states are too deep within the bandgap to significantly increase visible light activity, unlike nitrogen 1s states, which successfully overlap with valence band O2p states.

▼ Astrophysical observations are central to the quest for new physics including the search for dark matter. The search is based on identifying potential deviations from the Standard Model in the cosmic-ray and the electromagnetic spectrum of astrophysical sources. The deviations could either be signatures of dark matter or have consequences for our understanding of known sources. The last decade of precision measurements from detectors in space, such as the Fermi Gamma-ray Space Telescope, and the Alpha Magnetic Spectrometer for detecting cosmic rays aboard the International Space Station, have identified certain “anomalies” or unexpected spectral features, that challenge the standard models of how cosmic rays are produced and propagate through the Galaxy. Examples include an unexpectedly hard spectrum of cosmic-ray antiprotons at energies above a few hundred GeV, and an unexplained excess of very-high-energy gamma rays from the Sun. An excess of cosmic-ray antiprotons and a hard spectrum of gamma rays from the Sun also feature in the predictions of various models of dark matter annihilation. However, without a complete understanding of the antiproton spectrum, and the production mechanisms of solar gamma rays, it is impossible to differentiate new physics from the standard astrophysical foreground flux of these particles. Measuring these fluxes at energies that extend into the TeV range is an observational challenge that we explore in this thesis. The High AltitudeWater Cherenkov (HAWC) Observatory is a wide field-of-view array that is currently the only detector capable of making high-statistics measurements of cosmic rays and gamma rays at multi-TeV energies. This work uses data from HAWC collected between 2014–2017 to constrain two unique fluxes at the TeV scale: antiprotons in Galactic cosmic rays, and gamma rays from the quiescent Sun — both relevant foregrounds for astrophysical searches for physics beyond the Standard Model. Cosmic rays in the inner solar system are subject to deflection by the magnetic fields of the Earth and the Sun, affecting the observed deficit or “shadow” of the Moon/Sun. Cosmic rays also interact with the Sun’s atmosphere to produce a steady emission of gamma rays up to at least 200 GeV, though the exact underlying mechanism remains a puzzle. We present the strongest upper limits on the antiproton to proton ratio in TeV cosmic rays at 1% using the Moon shadow as a momentum/ charge discriminant. We also discuss our search for excess gamma rays from the Sun above 1 TeV, and present the resulting implications for models of dark matter capture and annihilation in the Sun. Our results constrain the steady gamma-ray emission from the Sun up to a few times 10−12 TeV cm−2 s−1 at 1 TeV. For dark matter annihilation with long-lived mediators in the Sun, we present the strongest upper limits on dark matter-proton scattering cross section up to ~10−45 cm2, which is a potential improvement of four orders of magnitude compared to direct-detection experiments for dark…

Neste trabalho, estudamos modelos cosmológicos em que a energia escura foi tratada como um campo de matéria que interage com a matéria escura. Três modelos distintos foram considerados. O primeiro trata tanto a matéria escura fria quanto a energia escura como fluidos perfeitos. O termo de interação entre eles é dado por uma expressão com origem fenomenológica que postulamos existir na equação de balanço entre esses dois fluidos. Dadas as equações no universo plano de Friedmann-Robertson-Walker (FRW), pudemos escrever uma versão covariante para as equações de balanço. Com isso, as equações de balanço em um universo de FRW perturbado linearmente foram obtidas. Isso, por sua vez, permitiu que a estabilidade das equações diferenciais obtidas fosse estudada. O segundo modelo tem origem em modelos de f(R). Esses modelos propõem uma generalização da Relatividade Geral ao considerar a ação da gravidade como um funcional do escalar de Ricci, R. Através de uma transformação conforme, foi possível reinterpretar os modelos de f(R) como modelos em que um campo escalar canônico, que representa a energia escura, interage com os campos da matéria. Através do princípio da ação, obtivemos as equações de movimento e o tensor de energia-momento para nosso sistema. Com o campo escalar sendo interpretado como um fluido perfeito, pudemos, por fim, obter equações de balanço entre fluidos perfeitos tanto no nível de fundo quanto no universo perturbado linearmente. O terceiro modelo começa com a lagrangiana, em um espaço-tempo de FRW, de um campo escalar canônico, que representa a energia escura, e um campo fermiônico de spin-1/2, que representa a matéria escura. Um termo de interação de Yukawa entre esses campos foi postulado existir na lagrangiana. Novamente através do princípio da ação, obtivemos as equações de movimento e o tensor de energia-momento para esses campos. Essas equações de movimento puderam, por fim, ser reescritas como equações de balanço entre fluidos perfeitos tanto no nível de fundo quanto no universo perturbado linearmente.

In this work we studied cosmological models in which the dark energy was treated as a field of matter that interacts with dark matter. Three different models were considered. The first one treats both the cold dark matter and the dark energy as perfect fluids. The interaction term between them is given by a expression with phenomenological origin that we postulated to exist in the balance equations between these two fluids. Given the equations in the flat Friedmann-Robertson-Walker (FRW) universe, we wrote a covariant version of the balance equations. Thus, the balance equations in a linearly perturbed FRW universe were obtained. This, in turn, allowed the stability of the obtained differential equations to be studied. The second model comes from f(R) models. These models propose a generalization of General Relativity by considering the action for gravity as a functional of the Ricci scalar, R. Through a conformal transformation, it was possible to reinterpret the f(R) models as models in which…
