Atacama Cosmology Telescope (ACT) Extragalactic Southern Sources Catalog
Listed in NASA Data Portal
The ACTSOUTH catalog is a multi-frequency, multi-epoch catalog of extragalactic sources, based on 150, 220 and 280 GHz observations carried out in 2008, 2009 and 2010 using the Millimeter Bolometric Array Camera on the Atacama Cosmology Telescope.
Description
The catalog contains 695 sources, found in a sky area of ~600 square degrees. It is obtained by cross-matching sources found in 11 sub-catalogs, one for each season and frequency band.
Also include are co-added data from ~150 and ~160 square degrees using 2 and 3 years of overlapping observations. The authors divide the sources into two populations, synchrotron and dusty emitters, based on their spectral behavior in the 150 - 220 GHz frequency range. They find 374 synchrotron sources and 321 dusty source candidates.

Cross-matching with catalogs from radio to X-ray results in 264 synchrotron sources (71%) and 89 dusty sources (28%) with counterparts, suggesting that 232 dusty candidates are not in existing catalogs. This table was ingested by the HEASARC in November 2023 based upon the files downloaded from the LAMBDA archive at <a href="lambda.gsfc.nasa.gov/product/act/act_south_cat_get.html">https://lambda.gsfc.nasa.gov/product/act/act_south_cat_get.html</a>.
