Discovery of X-rays from the composite supernova remnant G0.9+0.1 with the BeppoSAX satellite
Abstract
Using the BeppoSAX satellite we have obtained the first secure X-ray detection of the supernova remnant G0.9+0.1. The 1-10 keV spectrum can be described with an absorbed power law with alpha ~ 3 and N_H ~ 3*E(23) cm(-2) . The high column density supports a distance similar to that of the Galactic Center. The X-ray emission, with a luminosity LX ~ 10(35) d10(2) erg s(-1) , coincides with the central radio core, confirming the composite nature of this remnant. Though a search for periodic pulsations gave a negative result, the observed X-rays are probably related to the presence of a young radio pulsar at the center of G0.9+0.1.
