GBT24B-194

SZ observations of MaDCoWS clusters with diffuse radio emission at z=0.8-1.34

Abstract

We propose a follow-up of a pilot observations (project GBT23B-120) of 6 galaxy clusters at redshift z=0.8-1.34, selected from the Massive and Distant Clusters of WISE Survey (MaDCoWS). These clusters are located in the area currently covered by the LOFAR Two Metre Sky Survey (LoTSS), and show diffuse radio emission on the cluster scale. These clusters represent the most distant systems known so far hosting diffuse radio emission, challenging our understanding of magnetic field amplification and particle acceleration. The proposed GBT/MUSTANG-2 observations will provide the first study of the co-evolution of the thermal gas and magnetic fields in the densest environments in the Universe when the first large scale structures formed, i.e. when the Universe was only about 5 Gyr old.
