Rapid Quenching of Galaxies at Cosmic Noon

The Astrophysical Journal, 2023
The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and what physical mechanisms are involved.

Satellite dwarf galaxies: stripped but not quenched [PDF]

Astronomy and 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

The First Quenched Galaxies: When and How?

The Astrophysical Journal Letters
Many quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...

The star-formation activity of IllustrisTNG galaxies: main sequence, UVJ diagram, quenched fractions, and systematics

Monthly Notices of the Royal Astronomical Society, 2019
We select galaxies from the IllustrisTNG hydrodynamical simulations ($M_*>10^9~\rm M_\odot$ at $0\le z\le2$) and characterize the shapes and evolutions of their UVJ and star-formation rate -- stellar mass (SFR-$M_*$) diagrams.

Galaxy zoo: stronger bars facilitate quenching in star-forming galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACTWe have used Galaxy Zoo DECaLS (GZD) to study strong and weak bars in disc galaxies. Out of the 314 000 galaxies in GZD, we created a volume-limited sample (0.01 < z < 0.05, Mr < − 18.96) which contains 1867 galaxies with reliable volunteer bar classifications in the ALFALFA footprint.

Quenched Galaxies in Clusters of Galaxies and Their Outskirts [PDF]

Astrophysical Bulletin, 2020
Based on the SDSS data, the properties of galaxies with quenched star formation (QGs) within the "splashback"-radius of galaxy clusters $R_{\rm sp}$ and beyond it have been studied.

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.
