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 ...
Destruction of molecular gas reservoirs in early-type galaxies by active galactic nucleus feedback
(2009)
Residual star formation at late times in early-type galaxies and their progenitors must be suppressed in order to explain the population of red, passively evolving systems we see today. Likewise, residual or newly accreted ...
Galaxy Zoo: a sample of blue early-type galaxies at low redshift
(2009)
We report the discovery of a population of nearby, blue early-type galaxies with high star formation rates (0.5 < SFR < 50 M⊙ yr−1) . They are identified by their visual morphology as provided by Galaxy Zoo for Sloan Digital ...
