Letter to the Editor Discovery of X-rays from the composite supernova remnant G0.9+0.1 with the BeppoSAX satellite

Using theBeppoSAX satellitewe have obtained the first secureX–ray detection of the supernova remnantG0.9+0.1. The 1–10 keV spectrum can be described with an absorbed power law with α ∼ 3 andNH ∼ 3×1023 cm−2. The high column density supports a distance similar to that of the Galactic Center. The X-ray emission, with a luminosity LX ∼ 10d10 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.
