Resumen:
Radio relics are extended sources of diffuse radio emission typically found in the outskirts of non-relaxed galaxy clusters which are believed to trace merger shocks. We investigate if a mock relic sample, obtained from "zoom-in" galaxy cluster simulations, is able to match the properties of all known relics measured in the NRAO VLA Sky Survey (NVSS). The overall good agreement between NVSS and the mock sample suggests that properties of radio relics are indeed governed by merger shock fronts, emitting in a homogeneous fashion. Our study demonstrates that the combination of mock observations and data from upcoming radio surveys will allow to shed light on both the origin of radio relics and the nature of the intracluster medium.
