Abstract:
We are performing a uniform and unbiased imaging survey of the Large
Magellanic Cloud (LMC; ∼7°x7°) using the IRAC (3.6, 4.5, 5.8,
and 8um) and MIPS (24, 70, and 160um) instruments on board the Spitzer
Space Telescope in the Surveying the Agents of a Galaxy's Evolution
(SAGE) survey, these agents being the interstellar medium (ISM) and
stars in the LMC. This paper provides an overview of the SAGE Legacy
project, including observing strategy, data processing, and initial
results.
The observing strategy includes two epochs in 2005, separated by 3
months, that both mitigate instrumental artifacts and constrain source
variability. The SAGE data are nonproprietary. The data processing
includes IRAC and MIPS pipelines and a database for mining the
point-source catalogs, which will be released to the community in
support of Spitzer proposal cycles 4 and 5. We present initial results
on the epoch 1 data for a region near N79 and N83. The MIPS 70 and
160um images of the diffuse dust emission of the N79/N83 region reveal
a similar distribution to the gas emissions, especially the HI 21cm
emission.
