| Abstract |
GLIMPSE360 is a Spitzer Space Telescope Exploration Science Project that
is mapping the remaining 187 degrees of the Galactic Plane not
previously observed with Spitzer. The survey covers longitude l=65-265
degrees (excluding l =102-109 and l=76-82). The latitude range is 2.6
degrees, slightly wider than the previous GLIMPSE surveys (2 degrees).
The latitude center follows the
Galactic warp. Three visits on each sky position with 0.6 & 12s HDR
frames makes this survey 13 times more sensitive than the previous
GLIMPSE surveys of the inner Galactic plane. Even though we only have 2
IRAC bands in the post-cryogenic mission (3.6 and 4.5 microns) compared
to GLIMPSE (3.6, 4.5, 5.8, 8.0, and 24 micron from the MIPSGAL), the
combination of deeper exposures and lower confusion is allowing us to
achieve all the science goals we had hoped for, including: mapping the
edge of the stellar disk, and finding PAH bubbles from massive stars,
outflows from intermediate to high-mass Young Stellar Objects (YSOs),
low-to high-mass YSOs, stellar clusters, supernova remnants, infrared
dark clouds (from extinction fitting of stars rather than silhouettes of
PAH backgrounds), dusty evolved stars, and external galaxies in the Zone
of Avoidance.
As of Oct. 1, 2010, about 80% of the data have been taken, and of that,
about 70% have been processed at least once to produce source lists. We
will present preliminary results and some wickedly pretty (green)
pictures. Following the tradition of the previous GLIMPSE Legacy
programs, we will deliver enhanced products to the community, consisting
of high-quality point source lists and cleaned mosaic images. This
research is supported by NASA/JPL. |
