G332.5-5.6, a new Galactic supernova remnant

We present radio observations of the source G332.5-5.6, a candidate supernova remnant (SNR). Observations have been performed with the Australia Telescope Compact Array (ATCA) at two frequencies, 1.4 and 2.4 GHz. Our results confirm that G332.5-5.6 is an SNR, with a spectral index α = -0.7 ± 0.2 for...

Our results confirm that G332.5-5.6 is an SNR, with a spectral index α = -0.7 ± 0.2 for the whole source and an average fractional polarization of ∼35 per cent at 2.4 GHz.
