Galaxy cluster outskirts from the thermal SZ and non-thermal synchrotron link
Kaustuv Basu, Jens Erler, Martin Sommer +2
Galaxy cluster merger shocks are the main agent for the thermalization of the intracluster medium and the energization of cosmic ray particles in it. Shock propagation changes the…
Mpc-scale diffuse radio emission in two massive cool-core clusters of galaxies
Martin W. Sommer, Kaustuv Basu, Huib Intema +4
Radio halos are diffuse synchrotron sources on scales of ~1 Mpc that are found in merging clusters of galaxies, and are believed to be powered by electrons re-accelerated by the me…
ALMA-SZ Detection of a Galaxy Cluster Merger Shock at Half the Age of the Universe
Kaustuv Basu, Martin Sommer, Jens Erler +5
We present ALMA measurements of a merger shock using the thermal Sunyaev-Zel'dovich (SZ) effect signal, at the location of a radio relic in the famous El Gordo galaxy cluster at $z…
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…
