Radiative losses and cut-offs of energetic particles at relativistic shocks
read the original abstract
We investigate the acceleration and simultaneous radiative losses of electrons in the vicinity of relativistic shocks. Particles undergo pitch angle diffusion, gaining energy as they cross the shock by the Fermi mechanism and also emitting synchrotron radiation in the ambient magnetic field. A semi-analytic approach is developed which allows us to consider the behaviour of the shape of the spectral cut-off and the variation of that cut-off with the particle pitch angle. The implications for the synchrotron emission of relativistic jets, such as those in gamma ray burst sources and blazars, are discussed.

Constraining the slow-diffusion zone size and electron injection spectral index for the Geminga pulsar halo
A two-zone diffusion model fitted to HAWC morphology and spectrum data constrains Geminga's slow-diffusion zone to 30-70 pc and injection index p ≤ 2.17, reproducing AMS-02 positrons as a derived outcome.
