AGN-sCAN: zooming-in on the AGN-galaxy connection since the cosmic noon

PRIN 2022 Gitti

Abstract

The AGN-sCAN project consists of deep VLBA observations in the COSMOS field, targeting about 500 galaxies at high resolution. The primary goals of AGN-sCAN are: (A) assessing the incidence of radio-faint AGN in massive star-forming galaxies; (B) measuring the level of contamination from radio-faint AGN to the total radio emission. These steps will be crucial to provide unbiased constraints on the composition of the faint (sub-mJy) radio sky between AGN and star-forming galaxies, paving the way to the future SKA. At least two papers are foreseen by the AGN-sCAN team: one focusing on the survey paper and the other on the impact of radio-faint AGN on radio-SFR relations. The preliminary results obtained by the team seem to confirm the incidence of radio-faint AGN extrapolated from previous works, and a negligible contamination from radio-faint AGN to the total radio emission in star-forming galaxies.
