Abstract:
We present a catalog of compact sources derived from the QUaD Galactic
Plane Survey. The survey covers ∼800deg2 of the inner galaxy
(|b|<4°) in Stokes I, Q, and U parameters at 100 and 150GHz, with
angular resolutions of 5 and 3.5 arcmin, respectively. Five hundred
and twenty-six unique sources are identified in I, of which 239 are
spatially matched between frequency bands, with 53 (234) detected at
100 (150)GHz alone; 170 sources are identified as ultracompact HII
regions. Four sources are detected in polarized intensity P, of which
three have matching counterparts in I. Three of the polarized sources
lie close to the Galactic center, Sagittarius A*, Sagittarius B2, and
the Galactic Radio Arc, while the fourth is RCW 49, a bright HII
region. An extended polarized source, undetected by the source
extraction algorithm on account of its ∼0.5° size, is identified
visually, and is an isolated example of large-scale polarized emission
oriented distinctly from the bulk Galactic dust polarization.
Description:
QUaD was a 2.6m Cassegrain radio telescope. The observations reported
in this paper were made between 2007 July and October, with the
telescope decommissioned in late 2007. In total QUaD surveyed the
Galaxy for 40 days, covering a total of ∼800deg2.
