Abstract
Here we present the first catalogue of radio sources in GOODS-N based on ultra deep JVLAobservations at 5.5 GHz with sub-arcsec resolution. Near-IR identifications were obtained usingavailable deepKs-band observations, while IR colors were used to tentatively separate AGN fromstar-forming galaxies and passive elliptical galaxies. For the three classes of objects we present a preliminary analysis by their radio spectral properties. This work is part of the eMERGE legacy project, whose goal is to obtain a ultra-deep (sub-μJy rms), sub-arcsec (50-200mas) imaging oft he GOODS-N region at 1.4 and 5 GHz using combined JVLA andeMERLIN observations. Such dataset will be exploited to provide a resolved view of the GOODS-N radio source population in the high-redshift Universe where AGN cores can be spectro-morphologically separated from star forming galaxies.
