SUMMARY:Astronomy Lecture
DESCRIPTION:Physics & Astronomy Colloquium  Thursday, March 4, 4:00pm, Stevenson 4327    Professor Mark Devlin, University of Pennsylvania    Where Did Half the Starlight in the Universe Go?  We believe that approximately half of all the light from stars is absorbed and reprocessed by dust. The resulting emission is grey body with a temperature near 30 Kelvin. The COBE satellite made the first measurements of the resulting Far Infrared Background (FIRB), but since that time, we have been unable to resolve the background into individual galaxies. The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) was designed to do this job. Its three bands at 250, 350, and 500 microns span the peak in emission for galaxies at z=1. I will discuss the BLAST experiment and present results from our measurements of resolved and unresolved galaxies.
