The list of SNRs with their basic physical properties was based on the radio Catalogue of Galactic Supernova Remnants by Dave Green

Builds upon the List of Galactic SNRs Interacting with Molecular Clouds maintained by Bing Jiang and on the census of the youngest Galactic SNRs by Matthieu Renaud.

Entries have been cross-checked with the Pulsar Wind Nebula Catalog by Mallory Roberts, the SGR/AXP Catalog from the McGill Pulsar Group, and the Chandra Catalog of Galactic SNRs.

Image Credits

The new images component of SNRcat made use of data compiled from several resources, in addition to images made by the UofM SNR group for research and/or kindly provided by collaborators.

In the X-ray band, we acknowledge using data from Chandra, XMM-Newton and ROSAT, in addition to HEASARC resources maintained by NASA’s Goddard Space Flight Center.

In the radio band, the following resources were used: CHIPASS 1.4 GHz radio continuum map, Canadian Galactic Plane Survey (CGPS) and other data from the Dominion Radio Astrophysical Observatory, Southern Galactic Plane Survey, Effelsberg 100m Telescope and Stockert Galactic plane survey (2720 MHz) (via MPIfR’s Survey Sampler), Molonglo Observatory Synthesis Telescope (MOST) Supernova Remnant Catalogue (843 MHz), Sino-German 6 cm survey.
Additionally we acknowledge the use of NASA’s SkyView facility located at NASA Goddard Space Flight Center for the data from the 4850 MHz Survey/GB6 Survey, NRAO VLA Sky Survey, Sydney University Molonglo Sky Survey (843 MHz), and the Westerbork Northern Sky Survey (325 MHz Continuum).
Very Large Array (VLA) data were acquired via the NRAO Science Data Archive and the Multi-Array Galactic Plane Imaging Survey (MAGPIS).

We also acknowledge using the Canadian Astronomy Data Centre for access to some of the data shown in the Catalogue.
