Active Galactic Nuclei

All massive galaxies are now thought to contain a central supermassive black hole, that undergo periods of accreting gas and material, forming what is known as an Active Galactic Nuclei (AGN). AGN are some of the most luminous objects in the Universe and can observed at many different wavelengths in the electromagnetic spectrum (via X-ray, Optical, Infrared and Radio waves). 

Those which are detected at radio wavelengths (in MeerKAT surveys such as MIGHTEE) are known as radio-loud AGN. Understanding how radio-loud AGN evolve throughout cosmic history, and their role of quenching star formation in galaxies is one area of research conducted at UWC.
