Abstract

Photographs of galaxy M82 obtained in blue light show the existence of a previously unknown system of large-scale filaments extending 4000 parsec (1.2 X 10^(22) cm) above and below the fundamental plane of the galaxy along the minor axis. These filaments emit continuous radiation that is highly polarized, with the electric vector predominately perpendicular to the filamentary structure. A plausible interpretation is that the radiation is optical synchrotron emission caused by relativistic electrons spiraling in a large-scale magnetic field. To produce radiation in visual wavelengths, the electron energies must be in the range 10^3 to 10^4 Bev if the magnetic field is between 10^(-5) and 10^(-6) gauss.
