Local galaxies are broadly divided into two main classes, star-forming (gas-rich) and quiescent (passive and gas-poor). The primary mechanism responsible for quenching star formation in galaxies and transforming them into quiescent and passive systems is still unclear. Sudden removal of gas through outflows or stripping is one of the mechanisms often proposed. An alternative mechanism is so-called “strangulation”, in which the supply of cold gas to the galaxy is halted. Here we report an… 
Both starvation and outflows drive galaxy quenching
Star-forming galaxies can in principle be transformed into passive systems by a multitude of processes that quench star formation, such as the halting of gas accretion (starvation) or the rapid
Star Formation Quenching Timescale of Central Galaxies in a Hierarchical Universe
Central galaxies make up the majority of the galaxy population, including the majority of the quiescent population at . Thus, the mechanism(s) responsible for quenching central galaxies play a
INTERMITTENT SELF-SUSTAINING STAR FORMATION IN MASSIVE, LOW-REDSHIFT GALAXIES EXHIBITING A PEAK METALLICITY PLATEAU
The decline of star formation in massive low-redshift galaxies, often referred to as “quenching,” has been attributed to a variety of factors. Some proposals suggest that erupting active galactic
Star formation quenching in galaxies
The cosmic star formation rate density is peaked at $z\sim2$ and declines continuously since then, implying that the quenching of star formation has been the dominating process in galaxy evolution in
Bursting and quenching in satellite galaxies
The difference in stellar metallicity between red and blue galaxies with the same mass constrains the time-scale over which red galaxies ceased to form stars. Here we investigate this constraint
Quenching as a Contest between Galaxy Halos and Their Central Black Holes
Existing models of galaxy formation have not yet explained striking correlations between structure and star formation activity in galaxies, notably the sloped and moving boundaries that divide
GASP – XII. The variety of physical processes occurring in a single galaxy group in formation
GAs Stripping Phenomena in galaxies with MUSE (GASP) is a program aimed at studying gas removal processes in nearby galaxies in different environments. We present the study of four galaxies that are
Significance of bar quenching in the global quenching of star formation
The suppression of star formation in the inner kiloparsec regions of barred disk galaxies due to the action of bars is known as bar quenching. We investigate here the significance of bar quenching in
Gas Content Regulates the Life Cycle of Star Formation and Black Hole Accretion in Galaxies
Feedback from active galactic nuclei (AGNs) is expected to impact the amount of cold gas in galaxies by driving strong galactic winds, by preventing external gas inflows, or by changing the
Starburst and post-starburst high-redshift protogalaxies
Quenching of star-formation has been identified in many starburst and post-starburst galaxies, indicating burst-like star-formation histories (SFH) in the primordial Universe. Galaxies undergoing

Energy input from quasars regulates the growth and activity of black holes and their host galaxies
TLDR
Simulations that simultaneously follow star formation and the growth of black holes during galaxy–galaxy collisions find that, in addition to generating a burst of star formation, a merger leads to strong inflows that feed gas to the supermassive black hole and thereby power the quasar.
