Abstract

The balloon-borne large aperture sub-millimeter telescope (BLAST) has recently completed a highly successful long duration balloon flight from Antarctica. The instrument design incorporates a 2 m diameter primary mirror, with large format bolometer arrays operating at 250, 350 and 500 microns. By providing the first sensitive large-area (10 sq. degrees) surveys at these wavelengths, BLAST will address some of the most important galactic and cosmological questions regarding the formation and evolution of stars, galaxies and clusters.
