Both starvation and outflows drive galaxy quenching [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT 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 removal of gas in AGN-driven outflows.

The Way to Quench: Galaxy Evolution in A2142
Research in Astronomy and Astrophysics, 2023 Abstract We show how the star formation activity of galaxies is progressively inhibited from the outer region to the center of the massive cluster A2142. From an extended spectroscopic redshift survey of 2239 galaxies covering a circular area of radius ∼11 Mpc from the cluster center, we extract a sample of 333 galaxies with known ...

The Astrophysical Journal, 2023 How the environment influences the most massive galaxies is still unclear. To explore the effects of the environment on morphology and star formation in the most massive galaxies at high redshift, we select galaxies with stellar mass $\mathrm{log}({M}_ ...

Quenching Massive Galaxies with On-the-fly Feedback in Cosmological Hydrodynamic Simulations [PDF]
, 2011 Massive galaxies today typically are not forming stars despite being surrounded by hot gaseous halos with short central cooling times. This likely owes to some form of "quenching feedback" such as merger-driven quasar activity or radio jets emerging from

The impact of quenching on galaxy profiles in the
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We study specific star formation rate (sSFR) and gas profiles of star-forming (SF) and green valley (GV) galaxies in the simba cosmological hydrodynamic simulation. SF galaxy half-light radii (Rhalf) at z = 0 and their evolution (∝(1 + z)−0.78) agree with observations.

Significance of bar quenching in the global quenching of star formation [PDF]
A&A 628, A24 (2019), 2019 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 the global quenching of star formation in the barred galaxies and their transformation to passive galaxies in the local Universe.

The Growth of Red Sequence Galaxies in a Cosmological Hydrodynamic Simulation [PDF]
, 2012 We examine the cosmic growth of the red sequence in a cosmological hydrodynamic simulation that includes a heuristic prescription for quenching star formation that yields a realistic passive galaxy population today.
