TL;DR
This study utilizes ASKAP radio surveys to compile and confirm a catalog of Galactic supernova remnants and candidates, discovering new SNRs and refining classifications with polarization and spectral data.
Contribution
First comprehensive catalog of SNRs from EMU/POSSUM surveys, including new discoveries and candidate confirmations using polarization and spectral analysis.
Findings
Confirmed 8 SNR candidates via polarization and spectral indices.
Identified 6 new SNRs and 37 new candidates.
Demonstrated ASKAP's effectiveness in SNR detection and classification.
Abstract
We use data from the EMU (Evolutionary Map of the Universe) and POSSUM (Polarization Sky Survey of the Universe's Magnetism) radio southern sky surveys, conducted with the Australian Square Kilometre Array Pathfinder (ASKAP), to compile a catalogue of Galactic supernova remnants (SNRs) and candidate SNRs within the region of Galactic longitude, Galactic latitude, as well as an additional field along the Galactic plane, approximately Galactic longitude, Galactic latitude. In the areas studied, there are 44 known SNRs and 46 SNR candidates that have been previously identified in the radio. We confirm eight of these candidates as SNRs based on evidence of linear polarization or through the calculation of nonthermal spectral indices. Additionally, we…
