Abstract:
Studies of distant galaxies have shown that ellipticals and
large spirals (Schade et al., 1999ApJ...525...31S 1999ApJ...525...31S; Lilly et al.,
1998ApJ...500...75L 1998ApJ...500...75L) were already in place 8Gyr ago, leading to a
very modest recent star formation (Brinchmann & Ellis,
2000ApJ...536L..77B 2000ApJ...536L..77B) in intermediate mass galaxies
(3-30*1010M☉). This is challenged by a recent analysis
(Heavens et al., 2004Natur.428..625H 2004Natur.428..625H) of the fossil record of the
stellar populations of ∼105 nearby galaxies, which shows that
intermediate mass galaxies formed or assembled the bulk of their
stars 4 to 8Gyr ago. Here we present direct observational evidence
supporting this findings from a long term, multi-wavelength study of
195 z>0.4 intermediate mass galaxies, mostly selected from the Canada
France Redshift Survey (CFRS, Cat. VII/225).
