The Methodology of Modelling the Milky Way with Stellar Streams
In this thesis we examine the methodology of modelling the Milky Way using stellar streams. Using the orbit-fitting method we show that combining constraints from the Sagittarius stream with a suite of other photometric ...
Environmental Effects on Interacting Galaxy Pairs in the SDSS
The cause of varying galaxy interaction outcomes in different environments is investigated using a sample of over 505,000 Sloan Digital Sky Survey Data Release 7 galaxies at $0.01<z<0.20$. The aim is to distinguish the ...
The Evolution of Star Formation Activity in Cluster Galaxies Over 0.15 < z < 1.5
In this thesis, we explore 7.5 billion years of evolution in cluster galaxy star formation activity using a sample of 11 high-redshift (1 < z < 1.5) clusters from the IRAC Shallow Cluster Survey, and 25 low-redshift (0.15 ...
