X-rays from Supernova Remnants
A summary of X-ray observations of supernova remnants is presented including the explosion fragment A of the Vela SNR, Tycho, N132D, RX J08524622, the Crab Nebula and the ’bulls eye’, and SN 1987A, high-lighting the progress made with Chandra and XMMNewton and touching upon the questions which arise from these observations and which might inspire future research.
متن کاملSeparating Thermal and Nonthermal X - Rays in Supernova Remnants I : Total Fits to SN 1006 AD
The remnant of SN 1006 has an X-ray spectrum dominated by nonthermal emission , and pre-ASCA observations were well described by a synchrotron calculation with electron energies limited by escape. We describe the results of a much more stringent test: fitting spatially integrated ASCA GIS (0.6 – 8 keV) and RXTE PCA (3 – 10 keV) data with a combination of the synchrotron model sresc newly ported...
متن کاملBroad-band nonthermal emission from molecular clouds illuminated by cosmic rays from nearby supernova remnants
Molecular clouds are expected to emit non-thermal radiation due to cosmic ray interactions in the dense magnetized gas. Such emission is amplified if a cloud is located close to an accelerator of cosmic rays and if energetic particles can leave the accelerator site and diffusively reach the cloud. We consider here the situation in which a molecular cloud is located in the proximity of a superno...
متن کاملHadronic Gamma Rays from Supernova Remnants
A gas cloud near a supernova remnant (SNR) provides a target for pp-collisions leading to subsequent γ-ray emission through π-decay. The assumption of a power-law ambient spectrum of accelerated particles with index near –2 is usually built into models predicting the spectra of very-high energy (VHE) γ-ray emission from SNRs. However, if the gas cloud is located at some distance from the SNR sh...
متن کاملX-ray synchrotron emission from supernova remnants
X-ray synchrotron emission tells us of the highest energy reached by accelerated electrons. In a few supernova remnants (SN 1006, G347.3−0.5) this is the dominant form of X-ray radiation, but in most it is superposed to the dominant thermal emission. Thanks to the spectro-imaging capability of Chandra and XMM-Newton, X-ray synchrotron emission has now been unambiguously detected in most young s...
