A search for broad band H I emission from clusters of galaxies
Abstract
Using the Dwingeloo 25 m radio telescope, 21-cm spectra having an instantaneous bandwidth of 60 MHz (=13,000 km/s) with a resolution of 1 MHz (=210 km/s) for the Perseus, Cancer, Coma and A 1367 clusters of galaxies have been obtained. Upper limits on optically thin H I emission within a 36 arc min beam correspond to about 2 x 10 to the 11th solar masses or 0.0001 of the mass required to bind the larger clusters.
