A new catalogue of 125 galactic SNRs is presented. A surface brightness-diameter relationship, corrected for variation in height I z I above the galactic plane, is derived and applied to the catalogue to yield I z I-corrected distances and diameters. A birth rate of about one every 30 or 40 years is indicated from the number-diameter diagram.
Parkes 2·7 and 5·0 GHz polarization maps have been combined to obtain distributions of magnetic field, Faraday rotation and depolarization for 20 supernova remnants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
