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…
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…
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…
