A revised Galactic supernova remnant catalogue

TL;DR

This paper presents an updated catalogue of 274 Galactic supernova remnants, highlighting that newly identified remnants tend to be faint, consistent with observational selection effects.

Contribution

The paper provides a revised, comprehensive catalogue of Galactic SNRs with statistical analysis, improving data accuracy and completeness.

Findings

Recent SNRs are generally faint, supporting selection effect hypotheses.

The catalogue includes 274 SNRs with updated parameters.

Statistical insights into SNR properties are provided.

Abstract

A revised catalogue of 274 Galactic supernova remnants (SNRs) is presented, along with some simple statistics of their parameters. It is shown that the remnants that have recently been identified are generally faint, as is expected from the selection effects that apply to the identification of remnants.
