A revised catalogue of 294 Galactic supernova remnants

Understand

A revised catalogue of Galactic supernova remnants (SNRs) is presented, along with some simple statistics of their properties.

• Six new SNRs have been added to the catalogue since the previous published version from 2014, and six entries have been removed, as they have been identified as HII regions, leaving the number of entries in the catalogue at 294.
• Some simple statistics of the remnants in the catalogue, and the selection effects that apply, are discussed, along with some recently proposed Galactic SNR candidates.
