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…
A simple model for the size-evolution of elliptical galaxies
Sadegh Khochfar, Joseph Silk
We use semi-analytical modelling of galaxy formation to predict the redshift-size-evolution of elliptical galaxies. Using a simple model in which relative sizes of elliptical galax…
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…
