Abstract (from CDS):

We report the Australian Square Kilometre Array Pathfinder discovery of a new Galactic supernova remnant (SNR) candidate G308.73+1.38, which we name Raspberry. This new SNR candidate has an angular size of 20.'7 × 16.'7, and we measure a total integrated flux of 407 ± 50 mJy. We estimate Raspberry's most likely diameter of 10-30 pc which would place it at a distance 3-5 kpc, in the near side of the Milky Way's Scutum-Centaurus Arm. We also find a Stokes-V point source close to the center of Raspberry with a ∼5σ significance. This point source may be the remaining compact source, a neutron star, or possibly a pulsar, formed during the initial supernova event.
