The Most Unbiased Census of Star Formation in the Milky Way

Yancy Shirley

Dept. of Astronomy and Steward Observatory, University of Arizona

The Bolocam Galactic Plane Survey is a survey of 1.1 mm continuum in the Milky Way's first and second quadrants. Emission from cold dust grains can be seen in dense clumps across the Galaxy. Over 8400 objects have been identified in the BGPS. The objects represent the most complete census of star forming regions (both actively forming stars and regions that are pre-protostellar); however, little is known about the physical properties of this new population of star-forming clumps. Fundamental properties such as the size, mass, and luminosity require knowledge of the distance. I shall describe our efforts to determine the distance from followup observations of molecular gas in the clumps using the Submillimeter Telescope (SMT) on Mount Graham.

Refreshments at 11:00 AM. Seminar begins at 11:10 AM.
