Studying the Effect of Shock Obliquity on the -ray and Diffuse Radio Emission in Galaxy Clusters
Denis Wittor, Franco Vazza, Marcus Brüggen
Observations of diffuse radio emission in galaxy clusters indicate that cosmic-ray electrons are accelerated on Mpc scales. However, protons appear to be accelerated less eff…
On the non-thermal energy content of cosmic structures
Franco Vazza, Denis Wittor, Marcus Brüggen +1
1) Background: the budget of non-thermal energy in galaxy clusters is not well constrained, owing to the observational and theoretical difficulties in studying these diluted plasma…
Testing cosmic-ray acceleration with radio relics: a high-resolution study using MHD and tracers
Denis Wittor, Franco Vazza, Marcus Brüggen
Weak shocks in the intracluster medium may accelerate cosmic-ray protons and cosmic-ray electrons differently depending on the angle between the upstream magnetic field and the sho…
Constraining the efficiency of cosmic ray acceleration by cluster shocks
F. Vazza, M. Brueggen, D. Wittor +3
We study the acceleration of cosmic rays by collisionless structure formation shocks with ENZO grid simulations. Data from the FERMI satellite enable the use of galaxy clusters as…
