Abundance Matching with the Galaxies of the Virgo Cluster and the Stellar-to-Halo Mass Relation
(University of Waterloo, 2012-09-27)Using data from the Next Generation Virgo Cluster Survey and high-resolution simulations of Virgo cluster-like halos, we determine the stellar-to-halo mass relation (SHMR) for subhalos, using the technique of abundance ... -
Local Group Analogues
(University of Waterloo, 2012-09-27)The abundance of satellite galaxies is a critical small-scale test of the standard cosmological model. From comparing the predictions of structure formation in simulations with observations of Local Group dwarf galaxies ... -
Modified Gravity and the Phantom of Dark Matter
(University of Waterloo, 2009-08-13)Astrophysical data analysis of the weak-field predictions support the claim that modified gravity (MOG) theories provide a self-consistent, scale-invariant, universal description of galaxy rotation curves, without the need ... -
Probing the dark universe with gravitational lensing
(University of Waterloo, 2018-09-17)Since its early success as an experimental test of the theory of general relativity in 1919, gravitational lensing has come a long way and is firmly established as an indispensable element for many astrophysical applications. ... -
Satellite Dynamics in Dark Matter Halos
(University of Waterloo, 2010-09-01)I have used an analytic model of tidal interactions to predict the evolution of a substructure in a static dark matter halo. Given the initial conditions of the satellite and background halo, the model predicts with high ...
