Suppression of star formation in early-type galaxies by feedback from supermassive black holes
Kevin Schawinski, Sadegh Khochfar, Sugata Kaviraj +21
Detailed high-resolution observations of the innermost regions of nearby galaxies have revealed the presence of supermassive black holes1. These black holes may interact with their…
The Physical Nature of Lyman Alpha Emitting Galaxies at z=3.1
Eric Gawiser, Pieter G. van Dokkum, Caryl Gronwall +20
We selected 40 candidate Lyman Alpha Emitting galaxies (LAEs) at z ~=3.1 with observed frame equivalent widths >150A and inferred emission line fluxes >2.5x10^-17 ergs/cm^2/s from…
The effect of environment on the UV colour-magnitude relation of early-type galaxies
K. Schawinski, S. Kaviraj, S. Khochfar +23
We use \textit{GALEX} (Galaxy Evolution Explorer) near-UV (NUV) photometry of a sample of early-type galaxies selected in \textit{SDSS} (Sloan Digital Sky Survey) to study the UV c…
UV-optical colours as probes of early-type galaxy evolution
S. Kaviraj, K. Schawinski, J. E. G. Devriendt +25
We have studied ~2100 early-type galaxies in the SDSS DR3 which have been detected by the GALEX Medium Imaging Survey (MIS), in the redshift range 0 < z < 0.11. Combining GALEX UV…
