The initial results from a program to map the thermal far-infrared emission from dusty elliptical galaxies are presented. Using the Yerkes 60-Channel Far-Infrared Camera on the Kuiper Airborne Observatory we have imaged three elliptical galaxies at 160mu with a resolution of 44('') (NGC 5666, NGC 6524, and the interacting system NGC 7463/4/5) and one at 100mu with a resolution of 25('') (NGC 6524). Observations of NGC 1275 (Per A) are scheduled for December 1993 and may also be discussed. The E/S0 system NGC 6524 is dominated by a central point source at both 100 and 160mu with a dust temperature of 29(deg) K, in agreement with IRAS data and recent submillimeter observations of the central regions from the James Clark Maxwell Telescope on Mauna Kea. In addition, NGC 6524 shows low-level extended dust emission at 160mu which is not detected at 100mu . The temperature of this dust is apparently less than 20(deg) K. Preliminary results from JCMT submillimeter observations of other dusty ellipticals may also be presented. This research was supported by NASA grant NGR 14-001-227 to the University of Chicago.
