Did most present-day spirals form during the last 8 Gyr? A formation history with violent episodes revealed by panchromatic observations. Hammer F., Flores H., Elbaz D., Zheng X.Z., Liang Y.C., Cesarsky C. <Astron. Astrophys., 430, 115-128 (2005)> =2005A&A...430..115H

This is challenged by a recent analysis (Heavens et al., 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). File Summary:
