Over the course of two flights, the Balloon-borne Large ApertureSubmillimeter Telescope (BLAST) made resolved maps of seven nearby (<25 Mpc)galaxies at 250, 350, and 500 microns. During its June 2005 flight from Sweden,BLAST observed a single nearby galaxy, NGC 4565. During the December 2006flight from Antarctica, BLAST observed the nearby galaxies NGC 1097, NGC 1291,NGC 1365, NGC 1512, NGC 1566, and NGC 1808. We fit physical dust models to acombination of BLAST observations and other available data for the galaxiesobserved by Spitzer. We fit a modified blackbody to the remaining galaxies toobtain total dust mass and mean dust temperature. For the four galaxies withSpitzer data, we also produce maps and radial profiles of dust column densityand temperature. We measure the fraction of BLAST detected flux originatingfrom the central cores of these galaxies and use this to calculate a "corefraction," an upper limit on the "AGN fraction" of these galaxies. We also findour resolved observations of these galaxies give a dust mass estimate 5-19times larger than an unresolved observations would predict. Finally, we areable to use these data to derive a value for the dust mass absorptionco-efficient of kappa = 0.29 +/-0.03 m^2 kg^-1 at 250 microns. This study is anintroduction to future higher-resolution and higher-sensitivity studies to beconducted by Herschel and SCUBA-II.
