The drivers of AGN activity in galaxy clusters: AGN fraction as a function of mass and environment
K. A. Pimbblet, S. S. Shabala, C. P. Haines +2
[Abridged] We present an analysis of optical spectroscopically-identified AGN to M*+1 in a sample of 6 self-similar SDSS galaxy clusters at z=0.07. These clusters are specifically…
Infrared spectroscopy of nearby radio active elliptical galaxies
Jeremy Mould, Tristan Reynolds, Tony Readhead +7
In preparation for a study of their circumnuclear gas we have surveyed 60% of a complete sample of elliptical galaxies within 75 Mpc that are radiosources. Some 20% of our nuclear…
Tidal interactions at the edge of the Local Group: New evidence for tidal features in the Antlia Dwarf Galaxy
Samantha J. Penny, Kevin A. Pimbblet, Christopher J. Conselice +3
Using deep B band imaging down to mu_{B} = 26 mag arcsec^{-2}, we present evidence for tidal tails in the Antlia Dwarf galaxy, one of the most distant members of the Local Group. T…
Star formation in luminous quasar host galaxies at z=1-2
David J. E. Floyd, James S. Dunlop, Marek J. Kukula +4
We present deep HST/WFPC2, rest-frame U images of 17 ~L* quasars at z=1 and z=2 (V and I bands respectively), designed to explore the host galaxies. We fit the images with simple a…
New Constraints on the Quasar Broad Emission Line Region
Andrea J. Ruff, David J. E. Floyd, Rachel L. Webster +2
We demonstrate a new technique for determining the physical conditions of the broad line emitting gas in quasars, using near-infrared hydrogen emission lines. Unlike higher ionisat…
