Black holes in cosmological spacetimes and alternative theories of gravity
(University of Waterloo, 2023-08-09)This thesis is dedicated to the study of spacetimes surrounding black holes within the context of cosmology, high energy physics and modified theories of gravity. We do this by applying and adapting modern numerical ... -
Cosmological Tests of Causal Set Phenomenology
(University of Waterloo, 2017-09-20)Causal Set Theory is an approach to Quantum Gravity that postulates that the fundamental structure of a spacetime manifold is a Lorentz Invariant discrete structure endowed with a causal order from which the geometry and ... -
Large-Scale Filaments From Weak Lensing
(University of Waterloo, 2015-10-01)In the context of non-linear structure formation, a web of dark filaments are expected to intersect the high density regions of the universe, where groups and clusters of galaxies will be forming. In this work we have ... -
Studying the largest scales in the Universe with the kinetic Sunyaev-Zel'dovich effect
(University of Waterloo, 2022-01-19)As we progress further into the era of precision cosmology, new avenues to test our fundamental models of the Universe are opening up. This Ph.D. thesis is concerned with the development and understanding of a technique ... -
Virtues of the Visible; Voluminous Vistas & Velocities
(University of Waterloo, 2014-08-11)Peculiar velocities are the motions of objects in excess of that resulting from the expansion of the Universe. They arise from gravitational interactions, and as such, probe the underlying distribution of dark matter on ...
