Abstract:
We present the results of a search for mid-infrared signs of star
formation activity in the 1.1mm sources in the Bolocam Galactic Plane
Survey (BGPS). We have correlated the BGPS catalog (Cat. J/ApJS/188/123)
with available mid-IR Galactic plane catalogs based on the Spitzer
Space Telescope GLIMPSE legacy survey (including Cat. J/AJ/136/2413
and the EGO cat. J/AJ/136/2391) and the Midcourse Space Experiment
(MSX) Galactic plane survey (RMS catalog, Hoare et al.
2004ASPC..317..156H 2004ASPC..317..156H). We find that 44% (3712 of 8358) of the BGPS
sources contain at least one mid-IR source, including 2457 of 5067
(49%) within the area where all surveys overlap (10°<l<65°).
Accounting for chance alignments between the BGPS and mid-IR sources,
we conservatively estimate that 20% of the BPGS sources within the
area where all surveys overlap show signs of active star formation. We
separate the BGPS sources into four groups based on their probability
of star formation activity. Extended Green Objects and Red MSX Sources
make up the highest probability group, while the lowest probability
group is comprised of "starless" BGPS sources which were not matched
to any mid-IR sources. The mean 1.1mm flux of each group increases
with increasing probability of active star formation.

Note (1): The BGPS source name is based on the Galactic coordinates of the
peak of the 1.1mm emission.
Note (2): The Galactic coordinates of the geometric centroid of the 1.1mm
emission.
Note (3): For sources unresolved compared to the beam, the radius is set to
an upper-limit equal to half the beam size, 16.5".
Note (4): Only young RMS types ("HII Region", "HII/YSO", "YSO", and
"Young/old star?") are included here.
