Title : MeerKAT observation of unique head-tail radio galaxy MRC 0600-399 and cosmic magnetism science in the SKA-1 era
Place : ES635& ZOOM

Abstract: The MeerKAT telescope, a precursor to the Square Kilometre Array (SKA), demonstrates its power in many astronomical fields. We observed MRC 0600-399 with the MeerKAT, a head-tail radio galaxy in the merging galaxy cluster Abell 3376. It revealed that the collimated jets show a 90-degree bend at the contact discontinuity and extend over 100 kiloparsecs from the point of the bend against ram pressure by cluster merger. Based on the observational results and MHD simulation study, we concluded that the ordered magnetic field bends the jets along the contact discontinuity. In my talk, I will introduce this and the latest works about MRC 0600-399 by MeerKAT. I will also briefly review cosmic magnetism science in the SKA-1 era.
