Galaxies living in rich environments are suffering different perturbations able to drastically
affect their evolution. Among these, ram pressure stripping, ie the pressure exerted by the …

In a growing number of galaxy clusters diffuse extended radio sources have been found.
These sources are not directly associated with individual cluster galaxies. The radio …

We present cosmological parameter constraints based on the final nine-year Wilkinson
Microwave Anisotropy Probe (WMAP) data, in conjunction with a number of additional …

Radio observations prove the existence of relativistic particles and magnetic field associated
with the intra-cluster-medium (ICM) through the presence of extended synchrotron emission …

In recent years, observations of the Sunyaev-Zeldovich (SZ) effect have had significant
cosmological implications and have begun to serve as a powerful and independent probe of …

Abstract We present LOw Frequency ARray observations of the Coma Cluster field at 144
MHz. The cluster hosts one of the most famous radio halos, a relic, and a low surface …

We calculate the one-point probability density distribution functions (PDF) and the power
spectra of the thermal and kinetic Sunyaev–Zeldovich (tSZ and kSZ) effects and the mean …

We present deep LOFAR observations between 120 and 181 MHz of the" Toothbrush"(RX
J0603. 3+ 4214), a cluster that contains one of the brightest radio relic sources known. Our …

Many galaxy clusters host megaparsec-scale radio halos, generated by ultrarelativistic
electrons in the magnetized intracluster medium. Correlations between the synchrotron …

The presence of relativistic electrons within the diffuse gas phase of galaxy clusters is now
well established, thanks to deep radio observations obtained over the last decade, but their …
