Star Formation in the Magellanic Clouds with the Herschel Key Program HERITAGE

The Spitzer SAGE surveys greatly increased the number of known massive and intermediate-mass young stellar objects (YSOs) in the LMC, but because it was conducted at mid-IR wavelengths, it missed the youngest, most deeply embedded sources, the so-called “Class 0” YSOs. HERITAGE (HERschel Inventory of The Agents of Galaxy Evolution) is a successor of the SAGE-LMC, SAGE-SMC, and SAGE-Spec Spitzer Legacy programs, and has been used to search for these highly embedded sources. HERITAGE, a Herschel Key Project that uses 237.7 hours of time, obtained SPIRE/PACS parallel imaging (110, 170, 250, 350, and 500 μm) of the Magellanic Clouds. We have carefully examined the HERITAGE images in order to identify highly embedded YSOs and fully account for the galaxies’ YSO population. Here we present the early results of the search.
