Diffusive acceleration in relativistic shocks: particle feedback
Yotam Nagar, Uri Keshet
The spectral index of particles diffusively accelerated in a relativistic shock depends on the unknown angular diffusion function , which itself depends on the par…

Diffusive shock-acceleration: breakdown of spatial diffusion and isotropy
Uri Keshet, Ofir Arad, Yuri Lyubarski
We point out that particles accelerated in a non-relativistic shock of compression ratio attain the standard, spectral index only under certain conditions. Prev…
