Gamma–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 کاملNeutron Stars in Supernova Remnants
In the following, we shall briefly summarize some facts and ideas concerning the presence of neutron stars in Supernova remnants. While sources similar to the Crab Nebula require the presence of a central energetic object, shell-type remnants such as Cas A are compatible with the presence of neutron stars releasing a weak relativistic wind. Supernova remnants are usually classified into two ext...
متن کاملSupernova Remnants in Molecular Clouds
Massive (>∼8 M ) stars may end their lives in the molecular clouds in which they were born. O-type stars probably have sufficient photoionizing radiation and wind power to clear a region > 15 pc in radius of molecular material. Early B stars (B1–B3 on the main sequence, or 8 − 12 M stars) are not capable of this and may interact directly with molecular gas. Molecular clouds are known to be clum...
متن کاملMagnetohydrodynamic turbulence in supernova remnants
We present estimates of the angular power spectra of the synchrotron radiation intensity fluctuations at 6 and 20 cm for the shell type supernova remnant Cas A and the filled-centre Crab supernova remnant. We find that the intensity fluctuations of both sources have a power law power spectrum with index −3.24 ± 0.03. This power law power spectrum is consistent with the magnetohydrodynamic turbu...
