Issue Date: | 2015 | Journal: | POS PROCEEDINGS OF SCIENCE | Volume: | The many facets of extragalactic radio surveys: towards new scientific challenges (EXTRA-RADSUR2015) | Number: | 267 | First Page: | 23 | 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. | Conference Name: | The many facets of extragalactic radio surveys: towards new scientific challenges (EXTRA-RADSUR2015) | Conference Place: | Bologna, Italy | Conference Date: | 20-23 October, 2015 | URI: | http://hdl.handle.net/20.500.12386/24061 | URL: | https://pos.sissa.it/267/023/ | ISSN: | 1824-8039 | DOI: | 10.22323/1.267.0023 | Bibcode ADS: | 2015fers.confE..23G | Fulltext: | open |
