Particle Acceleration by Magnetic Reconnection in AGNs and in the IGM
Particle Acceleration Magnetic Reconnection AGNs IGM
2011/10/9
There is no single mechanism by which fast particles are accelerated in astrophysical environments, and it is now recognized that the data require a rich variety of different mechanisms operating unde...

Particle Acceleration on Megaparsec Scales in a Merging Galaxy Cluster
Particle Acceleration Megaparsec Scales Merging Galaxy Cluster
2011/1/10
Galaxy clusters form through a sequence of mergers of smaller galaxy clusters and groups. Models of diffusive shock acceleration (DSA) suggest that in shocks that occur during cluster mergers, particl...
Self-initialised Fermi-1 acceleration by pitch-angle re-scattering of solar wind ions reflected from the parallel termination shock
anomalous cosmic ray process governing pick-up ions solar wind ions
2009/5/27
In a recent kinetic calculation a rather high amount of reflected ions was shown to occur at the solar wind termination shock under a parallel magnetic field orientation. The fate of these reflected i...
