HST imaging of four gravitationally lensed quasars
Nicholas F. Bate, Georgios Vernardos, Matthew J. O'Dowd +7
We present new HST WFPC3 imaging of four gravitationally lensed quasars: MG 0414+0534; RXJ 0911+0551; B 1422+231; WFI J2026-4536. In three of these systems we detect wavelength-dep…
Dwarf galaxies in the Perseus Cluster: further evidence for a disc origin for dwarf ellipticals
Samantha J. Penny, Duncan A. Forbes, Kevin A. Pimbblet +1
We present the results of a Keck-ESI spectroscopic study of six dwarf elliptical (dE) galaxies in the Perseus Cluster core, and confirm two dwarfs as cluster members for the first…
Probing the Upper Scorpius mass function in the planetary-mass regime
N. Lodieu, P. D. Dobbie, N. J. G. Cross +4
We present the results of a deep ZYJ near-infrared survey of 13.5 square degrees in the Upper Scorpius (USco) OB association. We photometrically selected ~100 cluster member candid…
The Clustering Of Galaxies Around Radio-Loud AGNs
Hauke Worpel, Michael J. I. Brown, D. Heath Jones +2
We examine the hypothesis that mergers and close encounters between galaxies can fuel AGNs by increasing the rate at which gas accretes towards the central black hole. We compare t…
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…
