(2015-12-10)As the CDMS (Cryogenic Dark Matter Search) experiment is scaled up to tackle new dark matter parameter spaces (lower masses and cross-sections), detector production efficiency and repeatability becomes ever more important. ...
-
(2009-06-02)The most popular way to achieve accelerated expansion of the universe is by introducing a scalar field in which motion of state varies with time. The accelerated expanded universe was first observed by Type Ia supernovae ...
-
(2022-07-25)The release of high-precision astrometric data from the Gaia space mission has revolutionized studies of the Milky Way’s halo substructures over the past few years. In this dissertation, I use this data to model the dynamics ...
-
(2009-06-09)Supercritical String Cosmology (SSC) introduces a time-dependent dilaton and a central charge deficit into the history of the development of the universe. To balance the effect of the dilaton and the central charge deficit, ...
-
(2017-07-24)The flipped SU(5) grand unification model with additional vector-like multiplets (FSU(5)) in the framework of General No-scale Supergravity is studied. The highly constrained soft supersymmetry breaking terms of the ...
-
(2012-10-19)A new formalism is presented for calculating the mean intensity spectrum and angular power spectrum of gamma-rays or neutrinos from extragalactic annihilating dark matter, taking into account the dependence of the relative ...
-
(2017-05-18)Understanding background events in a low-energy search for the WIMP dark matter candidate is critical to enable a viable search as these events must be reduced to avoid overwhelming the rare dark matter signal. The βˉ decay ...
-
(2023-07-26)Axions and axion-like pseudoscalar particles with dimension-5 couplings to photons exhibit coherent Bragg-Primakoff scattering with ordered crystals at keV energy scales. This provides for a natural detection technique in ...
-
(2008-05-25)Astronomical observations have shown that the amount of visible matter in the universe comprises only a fraction of the total mass of the universe. This extra mass is described as ``dark matter''. In this thesis we ...
-
(2020-01-08)Astronomical observations lead us to believe that dark matter constitutes the majority of the mass of the Universe, yet it has never been directly observed experimentally. The Super Cryogenic Dark Matter Search Experiment ...

We use N-body simulations to study the evolution of the Fornax dwarf spheroidal galaxy. Specifically, we study the effects of tides on the internal structure of Fornax, and its globular clusters. We adopt a cuspy NFW and ...
