We propose to obtain new MIPS Spectral Energy Distribution (SED) observations towards the nucleus of the starburst galaxy M82. M82 is a dwarf galaxy in the M81 group hosting a strong burst of star formation in its center. It is also the closest IR-bright starburst to our own Galaxy, and its proximity enables the detailed investigation of the dust emission even with MIPS-SED. We will join our data with existing IRS and other datasets to provide the most comprehensive investigation of the dust emission in this starburst, and its relation to the stellar populations that heat it. M82 is the template IR-bright starburst and a benchmark for distant galaxies studies. We will obtain a small mapping observation that is designed like the existing mapping observations made by the Spitzer Infrared Nearby Galaxies Survey (SINGS). Our proposed mapping observation requires only 1.6 hours of time. The galaxy M82 is nearby and very bright, but is the only galaxy in SINGS for which no nuclear map was obtained. Using the data we propose to obtain, we will generate a product similar to the other SED observations in SINGS, which we will make available to the SINGS team and to the community through the Spitzer Science Center.
