Abstract:
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 multiwavelength 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 (SFR), 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 the SFR 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 toward an underlying link between the stellar
mass, stellar growth, and supermassive black hole growth in a galaxy.
Description:
Our input galaxy sample was the Advanced Camera for Surveys General
Catalog (ACS-GC; Griffith+ 2012, J/ApJS/200/9). The ACS-GC is a
photometric and morphological catalog of 469501 galaxies imaged by the
ACS on HST in four surveys: the Galaxy Evolution from Morphologies and
SEDs (GEMS, Caldwell+ 2008, J/ApJS/174/136) survey, the Cosmological
Evolutionary Survey (COSMOS, Scoville+ 2007ApJS..172...38S 2007ApJS..172...38S), the Great
Observatories Origins Deep Survey (GOODS,
Dickinson & Giavalisco 2003mglh.conf..324D), and the All-wavelength
Extended Groth Strip International Survey (AEGIS,
Davis+ 2007ApJ...660L...1D 2007ApJ...660L...1D). The ACS-GC is dominated by COSMOS
galaxies due to its large field; COSMOS galaxies are 65% of all ACS-GC
galaxies while GEMS + GOODS-S, AEGIS, and GOODS-N galaxies constitute
15%, 15%, and 5% of ACS-GC galaxies, respectively.
In Section 3.1, we select AGNs using data from the Spitzer Space
Telescope using the NASA/IPAC Infrared Science Archive (IRSA) and the
Spitzer Enhanced Imaging Products (SEIP) Source List (see II/368).
In Section 3.2, we select AGNs using data from the Chandra X-ray
Observatory. We used data from the Advanced CCD Imaging Spectrometer
(ACIS) on Chandra, presented in the Chandra Source Catalog (CSC) v2.0
(see IX/57).
Through our selection process, we narrowed our initial sample of
345783 ACS-GC galaxies with redshifts to 3955 unique active galaxies
identified by IR and/or X-ray methods. Of these, 2094 and 1331 were
uniquely identified by Chandra and Spitzer, respectively, while 530
were identified by both telescopes.
