Stochastic Electron Acceleration in the TeV SNR RX J1713.7-3946 III: Time-Dependent Acceleration
We discuss the generic characteristics of stochastic particle acceleration by fully developed turbulence in collisionless plasmas and show that resonant interactions of particles with high-speed waves dominate the acceleration process. To produce the relativistic electrons inferred from the broadband spectrum of a few well-observed shell-type TeV supernova remnants (STTSNRs) in the leptonic sce...
متن کاملFine-structure in the nonthermal X-ray emission of SNR RX J1713.7−3946 revealed by Chandra
We present morphological and spectroscopic studies of the northwest rim of the supernova remnant RX J1713.7−3946 based on observations by the Chandra X-ray observatory. We found a complex network of nonthermal (synchrotron) X-ray filaments, as well as a ’void’ type structure – a dim region of a circular shape – in the northwest rim. It is remarkable that despite distinct brightness variations, ...
متن کاملMagnetic Field Amplification and Rapid Time Variations in Snr Rx J1713.7-3946
Evidence is accumulating suggesting that collisionless shocks in supernova remnants (SNRs) can amplify the interstellar magnetic field to hundreds of microgauss or even milli-gauss levels, as recently claimed for SNR RX J1713.7-3946. If these fields exist, they are almost certainly created by magnetic field amplification (MFA) associated with the efficient production of cosmic rays by diffusive...
متن کاملEvidence for TeV gamma - ray emission from the shell type SNR RX J 1713 . 7 − 3946
We report the results of TeV gamma-ray observations of the shell type SNR RX J1713.7−3946 (G347.3−0.5). The discovery of strong non-thermal X-ray emission from the northwest part of the remnant strongly suggests the existence of electrons with energies up to ∼ 100 TeV in the remnant, making the SNR a good candidate TeV gamma-ray source. We observed RX J1713.7−3946 from May to August 1998 with t...
متن کاملNonthermal X-radiation of SNR RX J1713.7−3946: The Relations to a Nearby Molecular Cloud
The recent X-ray and CO observations of RX J1713.7−3946 show that a significant fraction of the nonthermal X-ray emission of this unique supernova remnant associates, in one way or another, with a molecular cloud interacting with the west part of the shell. This adds a new puzzle in the origin of X-ray emission which cannot be easily explained within the standard model in accordance of which X-...
