Spatially Resolving the 350-μm Continuum, Cold-Dust Emission in Nearby Elliptical Galaxies: Recent Results
Abstract
SHARC II continuum observations at 350 μm are presented of the three galaxies in our sample of nearby elliptical galaxies, for which resolved CO gas disks have recently been detected with interferometry mapping. The SHARC II mapping results provide the first ever, clearly resolved FIR-submm continuum emission of any elliptical galaxy >40 Mpc. These new data are used in conjunction with archival Digital Sky Survey maps and other published data to determine dust associations with galactic structures, including dominant heating sources such as nuclear-activity, star-formation or diffuse-stellar radiation.
