Description
JWST has discovered an unexpected ubiquity of massive, active black holes at high redshift. Understanding their formation and the properties of their host galaxies is an ongoing endeavour. I will present first results from BlackTHUNDER, a JWST/NIRSpec-IFS Large Program to study broad-line AGN and their immediate surroundings during the first few billion years of cosmic history. Specifically, I will discuss the discovery of a triple AGN system at z~5, in context with other confirmed and candidate dual AGN at high redshift. Our results indicate that multiple massive black holes may be common in galaxies in the early Universe, and highlight the important role of IFU observations for their discovery and characterisation.
