The AGN-sCAN project builds on team-led VLBA 1.4 GHz observations (120-hours, PI: I. Delvecchio) taken in the COSMOS field. We targeted >500 star-forming galaxies at 0.5<z<5 over a sky area as large as the full Moon, reaching very high angular resolution (0.007" x 0.026") and sensitivity (down to 5 uJy/bm), that are sensitive to high surface brightness sources. 

This VLBA survey was designed to deliver accurate radio morphological information required to separate genuine star formation from radio-faint AGN emission, on a source-by-source basis, and provide an independent view of the composite nature of the sub-mJy radio sky.
