Abstract:
Using data from the all-sky Wide-Field Infrared Survey Explorer (WISE)
satellite, we made a catalog of over 8000 Galactic HII regions and HII
region candidates by searching for their characteristic mid-infrared
(MIR) morphology. WISE has sufficient sensitivity to detect the MIR
emission from H II regions located anywhere in the Galactic disk. We
believe this is the most complete catalog yet of regions forming
massive stars in the Milky Way. Of the ∼8000 cataloged sources, ∼1500
have measured radio recombination line (RRL) or Hα emission, and
are thus known to be H II regions. This sample improves on previous
efforts by resolving H II region complexes into multiple sources and
by removing duplicate entries. There are ∼2500 candidate H II regions
in the catalog that are spatially coincident with radio continuum
emission. Our group's previous RRL studies show that ∼95% of such
targets are H II regions. We find that ∼500 of these candidates are
also positionally associated with known H II region complexes, so the
probability of their being bona fide H II regions is even higher. At
the sensitivity limits of existing surveys, ∼4000 catalog sources show
no radio continuum emission. Using data from the literature, we find
distances for ∼1500 catalog sources, and molecular velocities for
∼1500H II region candidates.
Description:
WISE covers the entire sky in four photometric bands: 3.4um, 4.6um,
12um, and 22um at angular resolutions of 6.1", 6.4", 6.5", and 12",
respectively.

Note (1): If there are multiple WISE sources within the beam of an observed
position, all such WISE sources share the same line parameters.
Sources are <[ABB2014] WISE GLLL.ll+BB.bbb> in Simbad.
Note (2): Galactic HII region classification as follows:
K = Known;
G = Group;
C = Candidate;
Q = radio Quiet;
? = no radio data
Note (3): We group positionally associated HII region candidates with
sources from the known sample. In general, for group membership we
require that an HII region candidate be located on, or interior to,
the photodissociation region (PDR) of a known HII region (as seen at
12um), or that a known HII region be located on the PDR of an HII
region candidate. See section 3.2 for further explanations.

Note (5): To better characterize our WISE objects and to provide velocities
for those not yet observed in radio recombination lines or Hα
emission, we spatially correlate our WISE sources with molecular line
emission. We only attempt to correlate WISE sources that have angular
radii <4'. See section 4.
