Radio emission from merging galaxy clusters : characterizing shocks, magnetic fields and particle acceleration Weeren, R.J. van

Spectral index maps created using additional archival VLA observations show the presence of a 115 kpc head-tail source located roughly halfway the bright radio relic.

This interpreta- tion is based on (i) the location of the diffuse radio emission with respect to the X-ray emission, (ii) the presence of an elongated structure of galaxies in

It is proposed that these radio relics trace shock waves in the intracluster medium (ICM) created during a cluster merger event.. Within the shock waves particles are accelerated

Here we report the detection of a radio relic for which we find highly aligned magnetic fields, a strong spectral index gradient, and a narrow relic width, giving a measure of

In this section we present the simulated radio maps for a range of mass ratios, impact parame- ters, viewing angles and radial density/temperature profiles, and compare them to

The LOFAR 63 MHz image reveals some of the well-known tailed radio sources (A, B, F), the main relic (G and H), and part of the radio halo.. A hint of the long and straight

Door deze gegevens te combineren met al bekende radio relics zijn correlaties gevonden tussen verschillende eigenschappen van de bronnen, zoals hun grootte en de mate waarin
