Discovery of X–rays from the composite supernova remnant G0.9+0.1 with the BeppoSAX satellite
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 α ∼ 3 and NH ∼ 3×10 23 cm. The high column density supports a distance similar to that of the Galactic Center. The X-ray emission, with a luminosity LX ∼ 10 35d210 erg s , coincides with the central radio core, c...

متن کاملInverse Compton Emission from Galactic Supernova Remnants: Effect of the Interstellar Radiation Field
The evidence for particle acceleration in supernova shells comes from electrons whose synchrotron emission is observed in radio and X-rays. Recent observations by the HESS instrument reveal that supernova remnants also emit TeV g-rays, long-awaited experimental evidence that supernova remnants can accelerate cosmic rays up to the “knee” energies. Still, uncertainty exists whether these g-rays a...
متن کاملX-ray emission from the galactic center region supernova remnant G0.9+0.1
We report the results of a BeppoSAX observation of the composite supernova remnant G0.9+0.1, located in the Galactic Center region. This new observation, in which the core of G0.9+0.1 is observed on–axis, confirms our previous results obtained from a pointing in which the supernova remnant was serendipitously observed at a large off–axis angle. The better quality of the new data allows us to co...
متن کاملDiscovery of the Energetic Pulsar J1747–2809 in the Supernova Remnant G0.9+0.1
The supernova remnant G0.9+0.1 has long been inferred to contain a central energetic pulsar. In observations with the NRAO Green Bank Telescope at 2 GHz, we have detected radio pulsations from PSR J1747–2809. The pulsar has a rotation period of 52 ms, and a spin-down luminosity of Ė = 4.3×1037 erg s−1, the second largest among known Galactic pulsars. With a dispersion measure of DM = 1133 pc cm...
