Title: Star Formation Within the Giant HII Region W80

Abstract: We propose to obtain a contiguous 2.3^\circx2.3^\circ map of the extended HII region W80 using NEWFIRM in H2, JHK, and partial coverage in [Fe II]. Contained in this field of view are the little studied North American and Pelican nebulae, and a dark molecular cloud region referred to as the Gulf of Mexico. The distance to W80 (and regions therein) is about 550 pc making it the next nearest region similar to Orion. 2MASS extinction mapping reveals Av>5 mag over most of W80, and cores in several areas exceed 30 mag. Spitzer IRAC and MIPS have observed this entire complex, yielding catalogues of hundreds of potential YSOs. We have secured a couple of wide-field H2 2.12 (micron) images to search for shocks and outflows and have discovered dozens of highly embedded energetic protostellar outflows and jets distributed over the cloud complexes. The region rivals NGC 1333 known to harbor the highest outflows concentration. We image the entire complex, measuring SEDs (thereby allowing source classification), temperature and masses of the disks, and better define the extended structure and morphology of the intra-cloud medium, including IRDCs, pillars, and filaments.
