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 ...
Identifying the progenitor set of present-day early-type galaxies : A view from the standard model
(2009-08-01)
We present a comprehensive theoretical study, using a semi-analytical model within the standard LCDM framework, of the photometric properties of the progenitors of present-day early-type galaxies in the redshift range 0 ...
