عنوان فارسی Time Delays in Cosmic Ray Propagation
چکیده فارسی مقاله Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Furthermore deduction of CR sources without knowing CR time delays is not possible, so the magnitude of such delays will be discussed and compared to the characteristic time variation of possible cosmic ray sources.
