| We are involved in a Large program aiming at measuring the velocity fields of a representative sample of 100 massive galaxies at z=0.4-0.75, taken from the CDFS, the CFRS and the HDFS fields. It uses the unique multiple integral field units of FLAMES/GIRAFFE at VLT. Most intermediate redshift galaxies show anomalous velocity fields. The wealth of the data (HST/ACS, Spitzer, VLT/GIRAFFE and FORS2) in these fields allow to modelize the physical processes in each galaxy with an accuracy almost similar to what is done in the local Universe. I will discuss the way spiral galaxies have aggregated their stellar mass and angular momentum during the last 8 Gyrs. |
