An ALMA View of Molecular Gas in Brightest Cluster Galaxies
(University of Waterloo, 2018-09-25)In this thesis I use ALMA observations to map the distribution and kinematics of molecular gas in the brightest cluster galaxies of three galaxy clusters: 2A0335+096, RXJ0821+0752, and RXCJ1504-0248. The goal is to understand ... -
An alternative derivation of orbital-free density functional theory
(AIP, 2019-05-28)Polymer self-consistent field theory techniques are used to derive quantum density functional theory without the use of the theorems of density functional theory. Instead, a free energy is obtained from a partition function ... -
Aluminium-Palladium Transition Edge Sensors
(University of Waterloo, 2008-09-15)A superconducting Transition Edge Sensor (TES) can be used to make the most sensitive thermometer which operates in a very narrow temperature range. The thin film bi-layer fabrication details are discussed as well as ... -
Amended Model of Large Scale Dark Matter Structure
(University of Waterloo, 2020-09-03)Dark matter makes up around a quarter of the total energy density in the universe, but its identity remains elusive. Current ways of studying dark matter have centered around its macroscopic properties, such as density ... -
Amplitudes in the Spin Foam Approach to Quantum Gravity
(University of Waterloo, 2017-07-31)In this thesis, we study a Spin Foam model for 4D Riemannian quantum gravity, and propose a new way of imposing the simplicity constraints that uses the recently developed holomorphic representation. Rather than imposing ... -
