Simulations of isolated binary mergers of galaxy clusters are a useful tool to study the evolution of these objects. For exceptionally massive systems they even represent the only…
New detections of radio minihalos in cool cores of galaxy clusters
Simona Giacintucci, Maxim Markevitch, Tiziana Venturi +3
Cool cores of some galaxy clusters exhibit faint radio "minihalos." Their origin is unclear; their study has been limited by their small number. We undertook a systematic search fo…

Do radio relics challenge diffusive shock acceleration?
Franco Vazza, Marcus Brueggen
Radio relics in galaxy clusters are thought to be associated with powerful shock waves that accelerate particles via diffusive shock acceleration (DSA). Among the particles acceler…

We present polarisation data for 180 extragalactic sources extracted from the Australia Telescope 20 GHz (AT20G) survey catalog, and observed with the Australia Telescope Compact A…
Is the Sunyaev-Zeldovich effect responsible for the observed steepening in the spectrum of the Coma radio halo ?
G. Brunetti, L. Rudnick, R. Cassano +3
The spectrum of the radio halo in the Coma cluster is measured over almost two decades in frequency. The current radio data show a steepening of the spectrum at higher frequencies,…
Radio Jets Clearing the Way Through a Galaxy: Watching Feedback in Action
Raffaella Morganti, Judit Fogasy, Zsolt Paragi +2
The energy released by an active galactic nucleus (AGN) has a strong impact on the surrounding interstellar medium (ISM). This feedback is considered to be the regulating factor fo…
The Lockman Hole project: gas and galaxy properties from a stacking experiment
K. Geréb, R. Morganti, T. A. Oosterloo +2
We perform an HI stacking analysis to study the relation between HI content and optical/radio/IR properties of galaxies located in the Lockman Hole area. In the redshift range cove…
