The paper linked above notes in the introduction:
The authors are performing this calculation for an isotropic electron distribution. However, for my work, I am considering an electron population with a relativistic macroscopic bulk...
Recently, in my research, a question has arisen about the modification of the scattering frequency of a photon by a population of electrons, if those electrons are flowing at a considerable fraction of the speed of light.
Intuitively, to me, it seems that if a photon is directed into a...
