This facility is able to recover the velocity fields of almost all the emission line galaxies with IAB≤22.5 and W0(OII)≥15Å. In our sample, we find only 35% rotating disks. These rotating disks produce a Tully-Fisher relationship (stellar mass or MK versus Vmax which has apparently not evolved in slope, zero point and scatter since z=0.6). The only evolution found is a brightening of the B band luminosity of a third of the disks, possibly due to an enhancement of the star formation. The very large scatters found in previously reported Tully-Fisher relationships at moderate redshifts are caused by the numerous (65%) galaxies with perturbed or complex kinematics. Those galaxies include minor or major mergers, merger remnants and/or inflow/outflows and their kinematics can be easily misidentified by slit spectroscopy. Their presence suggests a strong evolution in the dynamical properties of galaxies during the last 7Gyr. Description: A total of 5 nights were allocated during the FLAMES/GIRAFFE guaranteed time to study the kinematics of distant galaxies (ESO runs 071.B-0322(A) and 072.A-0169(A)). File Summary:
