Witnessing the intracluster medium assembly at the cosmic noon in JKCS041
S. Andreon, C. Romero, H. Aussel +10
In this work we study the intracluster medium of a galaxy cluster at the cosmic noon: JKCS041 at z=1.803. A 28h long Sunyaev-Zel'dovich (SZ) observation using MUSTANG-2 allows us t…
Observations of compact sources in galaxy clusters using MUSTANG2
Simon R. Dicker, Elia S. Battistelli, Tanay Bhandarkar +26
Compact sources can cause scatter in the scaling relationships between the amplitude of the thermal Sunyaev-Zel'dovich Effect (tSZE) in galaxy clusters and cluster mass. Estimates…
