New perspectives on the supernova remnant G78.2+2.1

Abstract

Aims. The Galactic object G78.2+2.1 is a classical shell-type supernova remnant. Previous radio continuum studies have shown substantial variations in spectral index across the object. Existing studies of the neutral hydrogen are of relatively low resolution and sensitivity. Much higher sensitivity and resolution data from the Canadian Galactic Plane Survey justify a re-examination of the properties of this SNR.
