Statistical nature of astrophysical maser radiation for linear masers

Canadian Journal of Physics, 1992
The validity of the assumption of Gaussian statistics, a basis for the validity of use of the radiative transfer equation and for a lot of current astrophysical maser theories, is investigated. For tractability the investigation in this paper is confined to astrophysical linear masers, which are very important to astrophysical maser theories.

Polarization Properties of Astrophysical Masers [PDF]

, 1973
Observed interstellar OH and H2O maser lines at 18 cm and 1.35 cm exhibit unusual polarization properties. The OH emitters with the highest brightness temperatures, usually associated with H II regions, almost always show a high degree of circular polarization. The H2O maser line, on the other hand, is rarely polarized, and then only linearly polarized.
