GALICS II : The [ α/Fe]-mass relation in elliptical galaxies
(2009-10-03)
Aims. We test whether the mass-and σ-[α/Fe] relations in the stellar populations of early-type galaxies can be reproduced by a cosmologically motivated assembly history for spheroids.Methods. We implement a detailed treatment ...
Evidence for recent star formation in BCGs : A correspondence between blue cores and UV excess
(2009-05-01)
We present a joint analysis of near-ultraviolet (NUV) data from the GALEX (Galaxy Evolution Explorer) mission and (optical) colour profiles for a sample of seven brightest cluster galaxies (BCGs) in the Canadian Cluster ...
