Claims

C1strongest claim

We confirm the SNR candidate as a new supernova remnant, dubbed Abeona. We detect the presence of a faint, extended, bilateral radio shell of the size of around 30' diameter and ASKAP radio flux density of 1.5^{+1.5}_{-0.1} Jy with no obvious infrared counterparts.

C2weakest assumption

The identification as a supernova remnant rests on the assumption that the observed radio morphology, linear polarization, lack of infrared counterparts, and spatial coincidence with a GeV source are sufficient to rule out other origins such as a planetary nebula or H II region, without direct kinematic evidence of expansion or X-ray detection.

C3one line summary

Abeona is confirmed as a faint ~30 arcmin bilateral radio SNR shell with synchrotron polarization, flux density 1.5 Jy, and a spatially coincident 5.7-sigma GeV gamma-ray source.
