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 ...
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 ...
