Description
Radio surveys are unique tracers of black holes in the distant Universe. Only the most massive black holes ($10^8-10^9\,$M$_\odot$) can produce the synchrotron jets which are luminous enough to appear in relatively shallow all sky radio surveys. After stagnating for a decade or so, we have seen a renaissance in this field over recent years with the discovery of numerous radio-loud AGN in the first billion years. Surveys with the MWA have led to the discovery of the most luminous radio galaxy at z>5.5 and has characterised the radio spectra of many radio-loud active galactic nuclei (AGN) at higher redshifts including the most luminous, super-Eddington AGN at this epoch. I will briefly summarise the results to date as well present the motivation for continuing this search including discovering the early black holes which are too rare and massive to be found in the narrow JWST fields as well as the potential for studying the early interplay of the galaxies with the interstellar medium via the 21-cm forest with the SKA.
