It is only now, with low-frequency radio telescopes, long exposures with high-resolution X-ray satellites and gamma-ray telescopes, that we are beginning to learn about the physics in the periphery of...
Plasma damping effects on the radiative energy loss of relativistic particles
Landau-Pomeranchuk-Migdal effect Ter-Mikaelian effect radiative energy loss

The energy loss of a relativistic charge undergoing multiple scatterings while traversing an infinite, polarizable and absorptive plasma is investigated.
We discuss alternatives to the usual quantization of relativistic particles which result in discrete spectra for position and time operators
