G64.5+0.9: a new shell supernova remnant with unusual central emission

We present observations between 1.4 and 18 GHz con?rming that G64.5+0.9 is a new Galacticshell supernova remnant, using the Very Large Array and the Arcminute Microkelvin Imager.The remnant is a shell 8 arcmin in diameter with a spectral index of a = 0.47 ± 0.03 (witha de?ned such that ?ux density S...
