Radio galaxy surveys

Radio surveys give us a glimpse into the universe by showing the distribution of radio sources and their intensity of the radio sky. Galaxies and extragalactic sources make up a large portion of all radio sources in the sky. Radio emission from galaxies either come from star-formation, is related to the Active galactic nuclei (AGN) or a combination of both.

The resolving power of a radio survey is determined by the size and separation of the radio telescopes. The greater the resolving power, the more details one can seen and the more one can see  fainter sources. The radio surveys that are conducted with MeerKAT and other pathfinders will dive into see even more fainter galaxies that were only observed in optical and Infrared surveys. The SKA radio galaxy surveys will see radio galaxies much fainter than sources found in optical and Infrared surveys.
