Constraining the Properties of Sagittarius A* with the Event Horizon Telescope
(University of Waterloo, 2015-10-01)Sagittarius A* (Sgr A*) is a primary target for testing strong gravity, jet formation and black hole accretion for the the Event Horizon Telescope (EHT). Motivated by continued improvements of the observations from the ... -
Forays into Mathematical Physics
(University of Waterloo, 2007-09-27)Two different works in mathematical physics are presented: A construction of conformal infinity in null and spatial directions is constructed for the Rainbow-flat space-time corresponding to doubly special relativity. ... -
Horizon Thermodynamics from Einstein's Equation of State
(University of Waterloo, 2017-04-28)The striking resemblance between geometric theories of gravity and thermodynamics suggests a more fundamental relationship between the two seemingly distinct theories. It has been postulated that the radial Einstein ... -
Neutron Stars, the Exotica - From Modifying General Relativity to Strong Magnetic Fields
(University of Waterloo, 2015-12-22)The gravitational aether theory is a modification of General Relativity that decouples vacuum energy from gravity, and thus can potentially address the cosmological constant problem. The classical theory is distinguishable ... -
Probing the Unruh and Hawking effects using Unruh-DeWitt detectors
(University of Waterloo, 2017-10-18)Quantum field theory is so far the best description of the fundamental laws of Nature, yet it does not fully incorporates gravitation. The first attempt toward unifying the quantum field theory and gravity is a semi-classical ... -
Sensing the shape of spacetime: detector response and entanglement harvesting in curved space
(University of Waterloo, 2019-01-24)This thesis seeks to understand what information Unruh-DeWitt detectors can gain about the structure of spacetime. By coupling to the quantum state of a field on a curved space, the detectors can gain information about ...
