Far-infrared Fine-Structure Line Diagnostics of Ultraluminous Infrared Galaxies
Duncan Farrah, Vianney Lebouteiller, Henrik Spoon +16
We present Herschel observations of six fine-structure lines in 25 Ultraluminous Infrared Galaxies at z<0.27. The lines, [O III]52, [N III]57, [O I]63, [N II]122, [O I]145, and [C…
Evidence of Increased UV FeII Emission in Quasars in Candidate Overdense Regions
Kathryn A. Harris, G. M. Williger, L. Haberzettl +6
We present evidence for a skewed distribution of UV FeII emission in quasars within candidate overdense regions spanning spatial scales of ~ 50 Mpc at 1.11 < z < 1.67, compared to…
A structure in the early universe at z ~ 1.3 that exceeds the homogeneity scale of the R-W concordance cosmology
Roger G. Clowes, Kathryn A. Harris, Srinivasan Raghunathan +3
A Large Quasar Group (LQG) of particularly large size and high membership has been identified in the DR7QSO catalogue of the Sloan Digital Sky Survey. It has characteristic size (v…
The Cluster and Large Scale Environments of Quasars at z<0.9
Kathryn A. Harris
In this thesis, I present an investigation into the environments of quasars with respect to galaxy clusters, and environment evolution with redshift and luminosity. The orientation…
