Quantifying the Origin and Distribution of Intracluster Light in a Fornax-like Cluster
Kathryn A. Harris, Victor P. Debattista, Fabio Governato +9
Using a cosmological -body simulation, we investigate the origin and distribution of stars in the intracluster light (ICL) of a Fornax-like cluster. In a dark matter only simula…
Extreme star formation events in quasar hosts over
Lura K. Pitchford, Evanthia Hatziminaoglou, Anna Feltre +7
We explore the relationship between active galactic nuclei and star formation in a sample of 513 optically luminous type 1 quasars up to redshifts of 4 hosting extremely high…
The Geometry of the Infrared and X-ray Obscurer in a Dusty Hyperluminous Quasar
Duncan Farrah, Mislav Balokovic, Daniel Stern +24
We study the geometry of the AGN obscurer in IRAS 09104+4109, an IR-luminous, radio-intermediate FR-I source at , using infrared data from Spitzer and Herschel, X-ray data…
Star Formation in Luminous Quasars at 2<z<3
Kathryn Harris, Duncan Farrah, Bernhard Schulz +22
We investigate the relation between star formation rates () and AGN properties in optically selected type 1 quasars at using data from Herschel and the SDSS. W…
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…
