1990ApJ...361...63L RADIO ABSORPTION BY THE INTERGALACTIC MEDIUM ERIC J. LERNER Lawrenceville Plasma Physics Received 1989 July 19; accepted 1990 March 20 ABSTRACT The infrared-radio correlation for spiral galaxies has been used to measure the absorption of 1.49 GHz radiation by the intergalactic medium. Contrary to conventional expectation, a sample of 237 galaxies shows a strong inverse correlation of radio luminosity (at a given IR luminosity) with distance, L_r_ ~ D^-0.4^, over a range of distances from 0.7-55 Mpc. Strong absorption by the intergalactic medium is the only reasonable explanation of this correlation, which is statistically significant at the 2 x 10^-12^ level. Subject heading: galaxies: intergalactic medium
