Solinger, A.B., 1969: A blast-wave model for the explosion in the galaxy M82. Astrophys. J., 158, L25-L30, doi:10.1086/180425.

The radio and optical data pertaining to M82 were reviewed in a previous paper (Solinger 1969; hereinafter referred to as "Paper I"). It was shown that the polarized optical continuum detected at distances as far as 5' (approximately 5 kpc) from the center of the galaxy is probably not due to synchrotron radiation and that the lines observed are probably excited collisionally, not radiatively as previously supposed. Moreover, these data were shown to provide a basis for consideration of a new model for the explosion; the energy released gives rise to a shock wave and consequent hydrodynamic flow which propagates through the galactic and circumgalactic media. The heating and compression which accompany the shock provide the line-excitation mechanism. The polarization pattern observed can be accounted for by postshock Thomson scattering of light from an unobserved, optically bright, central nucleus. The nucleus, probably obscured by dust, has been estimated to be of about the brightness of a Seyfert nucleus.
