An Overabundance of Radio Active Galactic Nuclei in the SPT2349–56 Protocluster: Preheating the Intracluster Medium

Following the detection of a radio-loud active galactic nucleus (AGN) in the z = 4.3 protocluster SPT2349−56, we have obtained additional observations with the South African MeerKAT radio telescope in the S band (2.4 GHz) with the aim of further characterizing radio emission from amongst the ∼30 sub...
