High-mass stars and the active nuclei (black holes) within galaxies produce continuum emission centred at a wavelength close to 21 cm. This emission can be observed with MeerKAT. The MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey aims to gain new insights into the processes governing and linking these important energetic phenomena within galaxies. MIGHTEE will use MeerKAT to create deep images (primarily in radio continuum emission) of the extragalactic sky to explore the cosmic evolution of galaxies. This survey will probe the physics of black hole accretion, high-mass star formation, and the emergence of magnetic fields in galaxies – all in ways never done before.
