Star forming galaxies

Webb15 okt. 2024 · Astronomers refer to galaxies that rapidly form stars as starburst galaxies. NGC 4666’s starburst is likely due to gravitational interactions with its unruly neighbors – including the nearby galaxy NGC 4668 and a dwarf galaxy, which is a small galaxy made up of a few billion stars. Webb23 dec. 2012 · AGN activity in the form or jets, winds, or intense radiation can heat up the hydrogen gas in the galaxy or blow it out completely, thus preventing the gas from cooling and contracting to form stars (referred to as AGN feedback). In order to investigate the importance of AGN in quenching star formation, the authors study a sample of 123 …
