Active Galactic Nuclei and Galaxy Formation

The Astrophysical Journal, 1997
It is proposed that early jet-induced activity around active galactic nuclei (AGNs) is responsible for triggering large-scale star formation in protogalaxies and results in the formation of giant ellipticals and spheroids in the universe. Specifically, Begelman & Cioffi's model for overpressured cocoons expanding into protogalactic environs yields size
