We present X-ray and radio observations of the new Galactic supernova remnant ( SNR ) G306.3-0.9 , recently discovered by Swift . Chandra imaging reveals a complex morphology , dominated by a bright shock .
The X-ray spectrum is broadly consistent with a young SNR in the Sedov phase , implying an age of 2500 yr for a distance of 8 kpc , plausibly identifying this as one of the 20 youngest Galactic SNRs .
Australia Telescope Compact Array ( ATCA ) imaging reveals a prominent ridge of radio emission that correlates with the X-ray emission .
We find a flux density of \sim 160 mJy at 1 GHz , which is the lowest radio flux recorded for a Galactic SNR to date .
The remnant is also detected at 24 \mu m , indicating the presence of irradiated warm dust .
The data reveal no compelling evidence for the presence of a compact stellar remnant .
