A giant radio halo in the cool core cluster CL1821+643

A. Bonafede, H. T. Intema, M. Brüggen +8

Giant radio halos are Mpc-size sources found in some merging galaxy clusters. The synchrotron emitting electrons are thought to be (re)accelerated by plasma turbulence induced by t…

Multiple density discontinuities in the merging galaxy cluster CIZA J2242.8+5301

G. A. Ogrean, M. Brüggen, R. J. van Weeren +4

CIZA J2242.8+5301, a merging galaxy cluster at z=0.19, hosts a double-relic system and a faint radio halo. Radio observations at frequencies ranging from a few MHz to several GHz h…
