A New Supernova Remnant Over the Galactic Centre

Abstract

Improved images and a newly determined spectrum - from 80 MHz to 15 GHz - have clarified the nature of the radio source GO.33 +0.04 at the Galactic Centre. Its non-thermal spectral index and its shell-like morphology favour an interpretation that it is a supernova remnant. Furthermore, the absorption characteristics of the continuum spectrum at the lowest frequencies and its elongation along the plane suggest that, like Sgr A East, it is in physical proximity to the Galactic Centre.
