Radio Map of the Andromeda Galaxy

John M. MacLeod 1

1 Vermilion River Observatory, University of Illinois, Urbana

The University of Illinois radio telescope has resolved the 610.5 Mcy/sec disk component of radio emission from the large galaxy M 31 into several discrete concentrations. In two cases, these correspond to the crossing of the optical major axis by spiral arms. A spur of emission extends southeast from the galaxy near the minor axis.
