2008-2010 ACT extragal. point sources catalog
Listed in IVOA Registry (Virtual Observatory)
We present a multi-frequency, multi-epoch catalog of extragalactic sources.
Description
The catalog is based on 150, 220, and 280GHz observations carried out in 2008, 2009, and 2010 using the Millimeter Bolometric Array Camera on the Atacama Cosmology Telescope. We also present and release 280GHz maps from 2008 and 2010.
The catalog contains 483 sources found in a sky area of square degrees. It was obtained by cross-matching sources found in 11 sub- catalogs, one for each season and frequency band. We also include co-added data from and square degrees using two and three years of overlapping observations.

We divide the sources into two populations, synchrotron and dusty emitters, based on their spectral behavior in the 150-280GHz frequency range. We find 284 synchrotron sources and 183 dusty source candidates. Our cross-matching with catalogs from radio to X-ray results in 251 synchrotron sources (88%) and 92 dusty sources (51%) with counterparts and suggests that 91 dusty candidates are not in existing catalogs.
We study the variability and number counts of each population. In the case of synchrotron sources, we find year-to-year variability, with a mean value around 35%. As expected, we find no evidence of dusty source variability.
Our number counts generally agree with previous measurements and models, except for dusty sources at 280GHz, where some models overestimate our results.
