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…
The LOFAR Two-metre Sky Survey - I. Survey Description and Preliminary Data Release
T. W. Shimwell, H. J. A. Röttgering, P. N. Best +69
The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120-168 MHz imaging survey that will eventually cover the entire Northern sky. Each of the 3170 pointings will be observed for 8 hr…
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…
Tracing low-mass galaxy clusters with radio relics: the discovery of Abell 3527-bis
F. de Gasperin, H. T. Intema, J. Ridl +6
Galaxy clusters undergo mergers that can generate extended radio sources called radio relics. Radio relics are the consequence of merger-induced shocks that propagate in the intra…
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…
Propagation of Ultra High Energy Cosmic Rays in Extragalactic Magnetic Fields: A view from cosmological simulations
Stefan Hackstein, Franco Vazza, Marcus Brueggen +2
We use the CRPropa code to simulate the propagation of ultra high energy cosmic rays (with energy and pure proton composition) through extragalactic magnetic…
