Interstellar Matter in Early-Type Galaxies. I. IRAS Flux Densities
Abstract
The data from the IRAS satellite were co-added for ~ 1150 early-type galaxies with apparent magnitudes brighter than 14 mag. At 60 and 100 microns, ~ 45% of the ellipticals and 68% of the S0 galaxies are detected, showing that a large fraction of these galaxies contain cool interstellar matter.
