The Epoch of Reionization (EoR) is a period during the history of the Universe that as of today has been largely unconstrained by cosmological measurements. …
Dark matter is an essential ingredient in our modern understanding of the Universe. However, its fundamental role in cosmology is matched only by its conspicuous …
The last few years have seen significant interest in decaying dark matter. Specific models have been conjectured to account for observations that are not predicted …
The "E and B mode EXperiment," (EBEX) is a balloon-borne telescope which aims to measure the polarization of the cosmic microwave background radiation in three …
Part I introduces the discontinuous Galerkin (DG) method for solving hyperbolic equations. The introduction and the DG scheme will be given in the first two …
The quantities and properties of the dark constituents of the universe reveal much about the past and future development of the cosmos. It is thought …
The Primordial Inflation Explorer (PIXIE) is a proposed NASA-led mission designed to measure the polarization and intensity of the cosmic microwave background (CMB). PIXIE will …
In recent years, weak gravitational lensing has become an indispensable method for understanding the concentration of matter on the largest scales. Galaxy clusters, the largest …
Cosmology in the 21st Century has evolved into a precision science. While ΛCDM has been established as the standard cosmological model there are still unanswered …
Despite numerous attempts at explaining and experimentally probing dark matter, thus far only its gravitational effects have been observed. These gravitational effects leave us blind …
In this thesis I explore applications of non-standard cosmological and gravitational theories theories in different sectors. The thesis contains three main parts. The first is …
