We present the Advanced Camera for Surveys Active Galactic Nuclei (ACS-AGN)
Catalog, a catalog of 2585 active galactic nucleus (AGN) host galaxies that are
at redshifts 0.2<z<2.5 and that were imaged with the Hubble Space Telescope’s
Advanced Camera for Surveys (ACS). Using the ACS General Catalog (ACS-GC) as
our initial sample, we select an AGN subsample using Spitzer and Chandra data
along with their respective established AGN selection criteria. We then gather
further multi-wavelength photometric data in order to construct spectral energy
distributions (SEDs). Using these SEDs we are able to derive multiple AGN and
host galaxy properties, such as star formation rate, AGN luminosity, stellar
mass, and nuclear column density. From these data, we show that AGN host
galaxies tend to lie below the star-forming main sequence, with X-ray-selected
AGN host galaxies being more offset than IR-selected AGN host galaxies. This
suggests that there is some process, possibly negative feedback, in AGN host
galaxies causing decreased star formation. We also demonstrate that there is a
positive trend between star formation rate and AGN luminosity in AGN host
galaxies, in individual redshift bins and across all redshift bins, and that
both are correlated with the stellar mass of their galaxies. This points
towards an underlying link between the stellar mass, stellar growth, and SMBH
growth in a galaxy.
