Abstract:
We present a point-source catalog from 771deg2 of the South Pole
Telescope Sunyaev-Zel'dovich (SPT-SZ) survey at 95, 150, and 220GHz.
We detect 1545 sources above 4.5σ significance in at least one
band. Based on their relative brightness between survey bands, we
classify the sources into two populations, one dominated by
synchrotron emission from active galactic nuclei, and one dominated by
thermal emission from dust-enshrouded star-forming galaxies. We find
1238 synchrotron and 307 dusty sources. We cross-match all sources
against external catalogs and find 189 unidentified synchrotron
sources and 189 unidentified dusty sources. The dusty sources without
counterparts are good candidates for high-redshift, strongly lensed
submillimeter galaxies. We derive number counts for each population
from 1Jy down to roughly 11, 4, and 11mJy at 95, 150, and 220GHz. We
compare these counts with galaxy population models and find that none
of the models we consider for either population provide a good fit to
the measured counts in all three bands. The disparities imply that
these measurements will be an important input to the next generation
of millimeter-wave extragalactic source population models.
Description:
The South Pole Telescope (SPT) is a 10m telescope located at the
Amundsen-Scott South Pole station in Antarctica. At 150GHz (2mm), the
SPT has arcminute angular resolution and a 1deg2 diffraction-limited
field of view. The first survey with the SPT, designated as the SPT-SZ
survey, was completed in 2011 November and covers a ∼2500deg2 region
of the southern extragalactic sky in three frequency bands, 95, 150,
and 220GHz, corresponding to wavelengths of 3.2, 2.0, and 1.4mm.
This paper uses data from five fields observed by the SPT in 2008 and
2009. These are the same fields used for the CMB power spectrum
analysis in Keisler et al. (2011ApJ...743...28K 2011ApJ...743...28K).

Note (1): Uncorrected for flux density boosting.
Note (2): Deboosted flux density values encompassing 16%, 50%, and 84%
(68% probability enclosed, or 1σ for the equivalent normal
distribution) of the cumulative posterior probability density for
95GHz flux, as estimated using the deboosting procedure described
in Section 3.
Note (3): Fraction of the spectral index posterior probability density above
the threshold value of 1.5 (P(α150220>1.5). A value
of P>0.5 means the source is more likely to be "dust" dominated,
lower value that the source is synchrotron ("sync") dominated.
This is detailed in Section 3.6.
Note (4): External catalogs wherein a source has a match with an offset smaller
than the chosen association radius. As described in Section 4.5, we
choose an association radius of 1arcmin for all catalogs except WISE,
where we use 0.5arcmin. References are:
