Contribution
It introduces a simulation-based analysis of radio relics, linking shock waves in galaxy clusters to non-thermal radio emissions at multiple frequencies.
Findings
Predicted radio relic counts at 1.4 GHz and 120 MHz
Constraints for LOFAR and future radio telescopes
Correlation between shock regions and radio emissions
Abstract
We identify shocked gas in simulated galaxy clusters extracted from the MareNostrum Universe simulation (Gottloeber et al. 2006) assuming that shock waves are regions of electron acceleration. We perform flux number counts within the framework of the non-thermal emission model developed by Hoeft et al. (2008). Results are presented at two different observing frequencies, i.e. 1.4 GHz and 120 MHz, posing interesting constraints for LOFAR and upcoming radio telescopes.
