EXTREME DUST DISKS IN Arp 220 AS REVEALED BY ALMA
Abstract
We present new images of Arp 220 from the Atacama Large Millimeter/submillimeter Array with the highest combination of frequency (691 GHz) and resolution (0.″36 × 0.″20) ever obtained for this prototypical ultraluminous infrared galaxy. The western nucleus is revealed to contain warm (200 K) dust that is optically thick (τ434 μm = 5.3), while the eastern nucleus is cooler (80 K) and somewhat less opaque (τ434 μm = 1.7). We derive full width at …
