Temperature Variations of Cold Dust in the Triangulum Galaxy M 33

We present wide-field 1.1mm continuum imaging of the nearby spiral galaxy M 33, conducted with the AzTEC bolometer camera on ASTE.We show that the 1.1mm flux traces the distribution of dust with T ~ 20K. Combined with far-infrared imaging at 160µm, we derived the dust temperature distribution out to...
