An Overabundance of Radio-AGN in the SPT2349-56 Protocluster: Preheating the Intra-Cluster Medium
Scott C. Chapman, Roger P. Deane, Dazhi Zhou +22
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 MeerKAT in S-band (2.4 GHz…

Discovery of a Ultra Steep Spectrum Radio Halo in the MeerKAT-South Pole Telescope Survey
Isaac S. Magolego, Roger P. Deane, Kshitij Thorat +15
Radio halos are diffuse synchrotron sources that trace the turbulent intracluster medium (ICM) of galaxy clusters. However, their origin remains unknown. Two main formation models…
