Synchrotron Radiation from Electrons with a Pitch-angle Distribution

open access: yes, 2018
In most astrophysical processes involving synchrotron radiation, the pitch-angle distribution of the electrons is assumed to be isotropic. However, if electrons are accelerated anisotropically, e.g., in a relativistic shock wave with an ordered magnetic ...
