Abstract:
The new generation of multiwavelength surveys permits to describe in detail the properties of galaxies over a large range of redshifts. Here, we present the results of the VVDS-VLA Deep Field: the aim of this work is to investigate radio sources properties knowing a priori with great detail the optical behaviuor of the host galaxies and having as control sample the entire VVDS survey. In particular, we determined the the star formation, stellar mass and luminosity functions for radio galaxies divided broadly in AGN and star forming driven emission. Finally, we show that it is possible to estimate the star formation history of the Universe using the optical galaxies as tracers for the radio emission.
