Abstract
  • Improved images and a newly determined spectrum — from 80 MHz to 15 GHz — have clarified the nature of the radio source G0.33 + 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.
