英文摘要: Studies of distant galaxies have shown that ellipticals and large spirals (Schade et al. 1999, ApJ, 525, 31; Lilly et al. 1998, ApJ, 500, 75) were already in place 8 Gyr ago, leading to a very modest recent star formation (Brinchmann & Ellis 2000, ApJ, 536, L77) in intermediate mass galaxies (3-30 x 10(10) M.). This is challenged by a recent analysis (Heavens et al. 2004, Nature, 428, 625) of the fossil record of the stellar populations of similar to10(5) nearby galaxies, which shows that intermediate mass galaxies formed or assembled the bulk of their stars 4 to 8 Gyr 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). We show that recent and efficient star formation is revealed at IR wavelengths since similar to15% of intermediate mass galaxies at z > 0.4 are indeed luminous IR galaxies (LIRGs), a phenomenon far more common than in the local Universe. The star formation in LIRGs is sufficient in itself to produce 38% of the total stellar mass of intermediate mass galaxies and then to account for most of the reported stellar mass formation since z = 1.
