ADC_Keywords: Photometry, millimetric/submm ; Surveys ; Galactic plane ; Interstellar medium Keywords: ISM: clouds - stars: formation - submillimeter Abstract: We present first results from an unbiased 50deg2 submillimeter Galactic survey at 250, 350, and 500um from the 2006 flight of the Balloon-borne Large Aperture Submillimeter Telescope. The map has resolution ranging from 36" to 60" in the three submillimeter bands spanning the thermal emission peak of cold starless cores. We determine the temperature, luminosity, and mass of more than 1000 compact sources in a range of evolutionary stages and an unbiased statistical characterization of the population. From comparison with C18O data, we find the dust opacity per gas mass, κr=0.16cm2/g at 250um, for cold clumps. We find that 2% of the mass of the molecular gas over this diverse region is in cores colder than 14K, and that the mass function for these cold cores is consistent with a power law with index α=-3.22±0.14 over the mass range 14M<M<80M. Description: BLAST is described in detail in Pascale et al. (2008ApJ...681..400P). The data presented here are from the 2006 flight: a 12 day flight from McMurdo Station, Antarctica in 2006 December (BLAST06). BLAST06 is a 1.8m Cassegrain telescope, whose underilluminated primary mirror produces beams with full width at half-maximum (FWHM) sizes of 36", 42", and 60" at 250, 350, and 500um, respectively. The 50deg2 submillimeter map of a portion of the Galactic plane made with BLAST spans ∼10° in Galactic longitude and ∼5° in Galactic latitude in the constellation Vela, including the Vela Molecular Ridge (VMR).
