- Abstract
The Revised Third Cambridge Catalogue of Radio Sources (3CR) has been instrumental in the study of active galaxies and active galactic nuclei (AGN) for the past sixty years. The catalogue's publication led to the discovery of quasars and has shaped our understanding of extragalactic radio sources, including their morphologies, energy sources, and host galaxies. Extragalactic 3CR sources can be classified as high-power, efficiently accreting radio galaxies and quasars, or low-power, inefficiently accreting radio galaxies. Jets emitted by AGN can have a significant impact on the surrounding host galaxy, influencing star formation rates and overall structure. Recent studies have shown that every galaxy emits radio waves connected to stellar processes, challenging the distinction between radio-loud and radio-quiet galaxies. The question of what drives the formation of jets in active galaxies remains unanswered.
