The black hole information paradox in a brane world
(University of Waterloo, 2023-06-28)Recent progress in our understanding of the black hole information paradox has led to a new prescription for calculating entanglement entropy, which involves special subsystems in regions where gravity is dynamical, called ... -
Black Holes in Pseudo-Topological Gravity
(University of Waterloo, 2009-08-05)In the following, we build on previous work done on higher derivative gravity, in particular Lovelock gravity. The latter is a family of theories in higher space-time dimensions in which interactions involving higher ... -
Correlation Functions of Heavy Operators in AdS/CFT
(University of Waterloo, 2024-04-15)In this thesis we investigate the holographic dual description of correlation functions of heavy operators in conformal field theory. These heavy operators have scaling dimension that scales with the CFT central charge in ... -
Correlation harvesting in the presence of Unruh and Hawking effects
(University of Waterloo, 2023-07-14)Quantum field theory (QFT) in curved spacetime is a study of quantum fields under the influence of the relativistic motion of particles or spacetime curvature. The famous outcomes of this subject are the Unruh and Hawking ... -
Gravitational Thermodynamics: From Black Holes to Holography
(University of Waterloo, 2021-06-01)The subject of gravitational thermodynamics lies at the center of numerous fields of study, many of which may seem disconnected, yet have proven to be deeply entwined. This thesis examines two primary facets of this subject, ... -
Messier 87: A Laboratory for Exploring AGN Variability using the Event Horizon Telescope
(University of Waterloo, 2020-09-17)At a distance of 50 million light years at the heart of the Virgo cluster, lies the giant elliptical galaxy Messier 87. This galaxy has at its center a brilliant relativistic jet, observable at all wavelengths, and at the ... -
Probing High Energy Physics Through Gravitational Waves
(University of Waterloo, 2021-09-22)Over the last few years, gravitational wave detections have become ubiquitous, giving the physics community vast information about fundamental physics. As some of the universe’s highest energy events, neutron mergers ... -
Quantum Aspects of Black Holes: From Microstates to Echoes and Somewhere In-Between
(University of Waterloo, 2023-05-23)In this thesis we explore quantum aspects of black holes from a variety of perspectives. In part I of this thesis we are motivated by the black hole information paradox to explore the idea of gravitational wave echoes ... -
Quantum Black Holes in the Sky
(University of Waterloo, 2020-09-30)Black Holes are possibly the most enigmatic objects in our Universe. From their detection in gravitational waves upon their mergers, to their snapshot eating at the centres of galaxies, black hole astrophysics has undergone ... -
Symmetries in Black Hole Spacetimes
(University of Waterloo, 2022-11-30)This thesis covers the role of explicit and hidden symmetries in some selected topics on the properties and excitations of black hole spacetimes. To this end, the symmetries of classical physics in Lorentzian manifolds are ... -
Unifying Thermal Big Bang and Black Holes
(University of Waterloo, 2020-09-30)Theories that stand the test of constant bombardment of new (and old) ideas, observations and unexplained phenomena are hard to come by. Despite countless attempts over many years of trying, cosmology and gravitational ... -
Using Black Hole Environments as Laboratories for Testing Accretion and Gravity
(University of Waterloo, 2023-08-29)With the advent of the Event Horizon Telescope (EHT), we have the ability to observe the lensed emission from hot plasmas near event horizons. It contains entangled information about the turbulent magnetohydrodynamic ...
