The primary cosmic ray spectrum in supernova remnants from very high energy γ-ray data
Supernova remnants are likely to be the accelerators of the galactic cosmic rays. Assuming the correctness of this hypothesis, we develop a method to extract the parent cosmic ray spectrum from the VHE gamma ray flux emitted by supernova remnants (and other gamma transparent sources). We illustrate the use of this technique by applying it to the young SNR RX J1713.7-3946 which has been observed...
متن کاملGamma–ray Production in Supernova Remnants
The bulk of the cosmic rays up to about 100 TeV are thought to be accelerated by the 1st order Fermi mechanism at supernova shocks, producing a power-law spectrum. Both electrons and protons should be accelerated, but their ratio on acceleration is not well known. Recently, the EGRET instrument on the Compton Gamma Ray Observatory has observed supernova remnants IC 443 and γ Cygni at GeV energi...
متن کاملGamma-ray Production in Supernova Remnants
Supernova remnants are widely believed to be a principal source of galactic cosmic rays, produced by diffusive shock acceleration in the environs of the remnant’s expanding shock. This review discusses recent modelling of how such energetic particles can produce gamma-rays via interactions with the remnants’ ambient interstellar medium, specifically via neutral pion decay, bremsstrahlung and in...
متن کاملSupernova remnants in molecular clouds: on cosmic ray electron spectra
The particle acceleration process at a shock wave, in the presence of the second-order Fermi acceleration in the turbulent medium near the shock, is discussed as an alternative explanation for the observed flat synchrotron spectra of supernova remnants (SNRs) in molecular clouds. We argue that medium Alfvén Mach number shocks considered by Chevalier (1999) for such SNRs can naturally lead to th...
متن کاملGalactic Cosmic Rays from Supernova Remnants: I a Cosmic Ray Composition Controlled by Volatility and Mass-to-charge Ratio
We show that the Galactic Cosmic Ray source (GCRS) composition is best described in terms of (i) a general enhancement of the refractory elements relative to the volatile ones, and (ii) among the volatile elements, an enhancement of the heavier elements relative to the lighter ones; this mass dependence most likely reflects a mass-to-charge (A/Q) dependence of the acceleration efficiency; among...
