On the formation of massive galaxies : A simultaneous study of number density, size and intrinsic colour evolution in GOODS
(2009-07-01)
The evolution of number density, size and intrinsic colour is determined for a volume-limited sample of visually classified early-type galaxies selected from the Hubble Space Telescope/Advanced Camera for Surveys images ...
The role of minor mergers in the recent star formation history of early-type galaxies
(2009-04-01)
We demonstrate that the large scatter in the ultraviolet (UV) colours of intermediate-mass early-type galaxies in the local Universe and the inferred low-level recent star formation (RSF) in these objects can be reproduced ...
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 ...
