Faint Ring around the Spiral Galaxy M82

Arp, Halton

Abstract

Photography of fainter surface brightnesses than heretofore detected shows a very unusual feature in the vicinity of the spiral galaxy M81. If this faint feature is synchrotron radiation from electrons exploded by the neighboring galaxy, M82, then the existence of an overall magnetic field in M81 can be established and calculated at a few microgauss. Other properties of M81 and its companion are implied and can be derived from further observation.
