Mass and Environment as Drivers of Galaxy Evolution. IV. On the Quenching of Massive Central Disk Galaxies in the Local Universe [PDF]
Astrophysical Journal, 2021 The phenomenological study of evolving galaxy populations in Peng et al. has shown that star forming galaxies can be quenched by two distinct processes: mass quenching and environment quenching. To explore the mass quenching process in local galaxies, we

AGN-driven quenching of satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We explore the effect of active galactic nucleus (AGN) feedback from central galaxies on their satellites by comparing two sets of cosmological zoom-in runs of 27 haloes with masses ranging from 1012 to 1013.4$\rm {M}_{\odot}$ at z = 0, with (wAGN) and without (noAGN) AGN feedback.

The Roles of Mass and Environment in the Quenching of Galaxies [PDF]
The Astrophysical Journal, 2019 Abstract We study the roles of stellar mass and environment in quenching the star formation activity of a large set of simulated galaxies by taking advantage of an analytic model coupled to the merger tree extracted from an N-body simulation. The analytic model has been set to match the evolution of the global stellar mass function since

Estimation of the Galaxy Quenching Rate in the Illustris Simulation [PDF]
, 2020 Quenching is a key topic in exploring the formation and evolution of galaxies. In this work, we study the quenching rate, i.e., the variation in the fraction of quenched galaxies per unit time, of the Illustris-1 simulation.

Quenching star formation in cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 In order to understand the processes that quench star formation within rich clusters, we construct a library of subhalo orbits drawn from $ $CDM cosmological N-body simulations of four rich clusters. The orbits are combined with models of star formation followed by quenching in the cluster environment.

Filaments in VIPERS: galaxy quenching in the infalling regions of groups [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We study the quenching of galaxies in different environments and its evolution in the redshift range $0.43 \leq z \leq 0.89$. For this purpose, we identify galaxies inhabiting filaments, the isotropic infall region of groups, the field, and groups in the

Overconsumption, outflows and the quenching of satellite galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2014 Abstract The baryon cycle of galaxies is a dynamic process involving the intake, consumption and ejection of vast quantities of gas. In contrast, the conventional picture of satellite galaxies has them methodically turning a large gas reservoir into stars until this reservoir is forcibly removed due to external ram pressure. This picture

The Evolution of Environmental Quenching Timescales to $z\sim1.6$ [PDF]
, 2018 Using a sample of 4 galaxy clusters at $1.35 < z < 1.65$ and 10 galaxy clusters at $0.85 < z < 1.35$, we measure the environmental quenching timescale, $t_Q$, corresponding to the time required after a galaxy is accreted by a cluster for it to fully ...

Satellite dwarf galaxies: stripped but not quenched [PDF]
Astronomy & Astrophysics, 2019 In the Local Group, quenched gas-poor dwarfs galaxies are most often found close to the Milky Way and Andromeda, while star forming gas-rich ones are located at greater distances. This so-called morphology-density relation is often interpreted as the consequence of the ram pressure stripping of the satellites during their interaction with the Milky Way

Pegasus W: An Ultrafaint Dwarf Galaxy Outside the Halo of M31 Not Quenched by Reionization
The Astrophysical Journal, 2023 We report the discovery of an ultrafaint dwarf (UFD) galaxy, Pegasus W, located on the far side of the Milky Way–M31 system and outside the virial radius of M31.
