内容記述 | We report on the discovery of a non-thermal X-ray emission from the supernova remnant (SNR) W28. W28 is a cosmic ray accelerator from which GeV and TeV gamma-ray were detected. We analyzed the northeast part of W28, and found a power-law spectrum with a photon index of 2.4 (2.1-2.8) from an inner region which is probably non-thermal X-ray emission caused by particle acceleration. On the assumption that it is synchrotron X-ray, the cooling time of synchrotron photon is consistent with the age of W28 with a few micro-G magnetic field. On the other hand, we have no significant X-ray flux from one of the TeV gamma-ray emission region. Assuming a power-law spectrum with a photon index of 2.66, the same as in the TeV band, we obtained a 2-10 keV flux upper limit of 2.1 x 10(exp -14) ergs/s sq cm. Low brightness in X-ray and the coincidence of the molecular cloud and TeV gamma-ray emission site suggests that TeV gamma-ray is originated from accelerated protons. | |||||
