Far-infrared emission from the intracluster medium
IRAS images of 56 clusters of galaxies are examined for evidence ofdiffuse, extended FIR emission at 60 and 100 microns. Of these 56clusters, five show evidence of FIR excess, but at low levels ofsignificance. For A496 and MKW 1, this excess is attributable to thepresence of a strong point source at or near the position of the centralcD galaxy. In A2344, the observed 100-micron excess is the result of thepresence of a foreground cirrus concentration which coincides with thecluster. Examination of the sample as a whole indicates that clustersexhibit excess FIR emission at the 2-sigma level for apertures 4 and 10arcmin in diameter. FIR luminosities range from about 1-0 exp 9 solarluminosities for the smallest aperture to about 10 exp 14 solarluminosities for the entire cluster.
