Scientific paper

We seek imaging of the FORS deep field {FDF} with the ACS to determine morphological and structural parameters of a complete sample of 80 late-type galaxies brighter than R_ lim=23^m {corresponding to M_B^*+2 at z=0.5} selected there. We already obtained spectra and derived velocity curves of these galaxies using the ESO VLT. Only combined with the ACS HST observations this will allow us to establish the Tully- Fisher relation between luminosity and rotation of spirals at a mean redshift of 0.5 and therefore measure the luminosity and mass evolution of spiral and irregular galaxies within about half of the age of the Universe, strongly constraining current theories of galaxy formation and evolution. Several other important scientific projects based on the FDF, such as a study of the Fundamental Plane of field elliptical galaxies at 0.3, a study of the size and type evolution of high-z galaxies {up to z 5} and a study of galaxy-galaxy lensing will also benefit from these observations.
