Nonlinear Particle Acceleration at Reverse Shocks in Supernova Remnants
Without amplification, magnetic fields in expanding ejecta of young supernova remnants (SNRs) will be orders of magnitude below those required to shock accelerate thermal electrons, or ions, to relativistic energies or to produce radio synchrotron emission at the reverse shock. The reported observations of such emission give support to the idea that diffusive shock acceleration (DSA) can amplif...
متن کاملShocks and Particle Acceleration in Supernova Remnants: Observational Features
The last ten years a number of observational advances have substantially increased our knowledge of shock phenomena in supernova remnants. This progress has mainly been made possible by the recent improvements in X-ray and γ-ray instrumentation. It has become clear that some shell-type supernova remnants, e.g. SN 1006, have X-ray emission dominated by synchrotron radiation, proving that electro...
متن کاملParticle Acceleration in Supernova Remnants and Pulsar Wind Nebulae
While supernova remnants (SNRs) have long been considered prime candidates for the source of cosmic rays, at least to energies up to ∼ 10 eV, it is only over the past several years that direct evidence of such energetic particles in SNRs has been uncovered. X-ray observations of several shell-type SNRs have now revealed sites dominated by nonthermal emission, indicating an electron population w...

A White Paper submitted to Astro2010: The Astronomy and Astrophysics Decadal Survey based in part on " The Status and Future of Ground-based TeV Gamma-ray Astronomy " , a White Paper prepared at the request of the Division of Astrophysics of the American Physical Society to summarize the status and future of ground-based γ-ray astronomy. The images above illustrate the richness available to fut...
متن کاملParticle Acceleration in Supernova Remnants and the Production of Thermal and Nonthermal Radiation
Energetic particle production in supernova remnants (SNRs) through diffusive shock acceleration has long been suggested as a mechanism by which the bulk of cosmic rays with energies less than ∼ 10 eV are formed. If highly efficient, this process can have a significant effect on the X-ray emission from SNRs as well as their dynamical evolution. Here we investigate the expected modification to th...
