is a pivotal open issue of high-energy astrophysics. Supernova remnants are strong candidates to be the Galactic factory of cosmic rays , their blast waves being powerful particle accelerators . However, super ...
these reveal about the cosmic - ray acceleration properties of SNRs. Nonthermal processes and particle acceleration in supernova remnants Jacco Vink and Aya Bamba Abstract Shocks of supernova remnants (SNRs ...
We evaluate the current status of supernova remnants as the sources of Galactic cosmic rays . We summarize observations of supernova remnants, covering the whole electromagnetic spectrum and describe ...
Cosmic ray (CR) origin problem is briefly discussed. It is argued that CRs with energies up to 1017 eV are produced in galactic supernova remnants, whereas ultra high energy CRs are extragalactic. CR ...
Abstract: Galactic cosmic rays (CRs) are accelerated by astrophysical shocks , primarily supernova remnants (SNRs), via diffusive shock acceleration (DSA), an efficient mechanism that predicts power ...
We give a brief review of the origin and acceleration of cosmic rays (CRs), emphasizing the production of CRs at different stages of supernova evolution by the first-order Fermi shock acceleration ...
It is accepted that the shock acceleration mechanism can explain the non-thermal cosmic rays in supernova remnants, active galactic nuclei and gamma ray bursts. Especially, the importance ...
Abstract. Supernova remnants, owing to their strong shock waves, are likely sources of Galactic cosmic rays . Studies of supernova remnants in X- rays and gamma rays provide us with new insights ...
ABSTRACTGalactic cosmic rays (GCRs) are thought to be accelerated in strong shocks induced by massive star winds and supernova explosions sweeping across the interstellar medium. But the phase ...
to account for the energization of cosmic rays . It is proposed that cosmic rays can be accelerated up to 1014–1015 eV in successive perpendicular shock waves which appear inside supernova shells in our Galaxy ...
