Scientific paper

The authors have co-added the IRAS survey data at the positions of the brightest elliptical galaxies in the Revised Shapley-Ames Catalog to increase the sensitivity over that of the IRAS Point Source Catalog. More than half of the galaxies are detected at 100 μm with flux levels indicating, typically, 107 or 108M_sun; of cold interstellar matter. The presence of cold gas in ellipticals thus appears to be the rule rather than the exception.
