Bar quenching in gas-rich galaxies [PDF]

Astronomy & Astrophysics, 2018
Galaxy surveys have suggested that rapid and sustained decrease in the star-formation rate (SFR), “quenching”, in massive disk galaxies is frequently related to the presence of a bar. Optical and near-IR observations reveal that nearly 60% of disk galaxies in the local universe are barred, thus it is important to understand the relationship between ...

CANDELS Sheds Light on the Environmental Quenching of Low-mass Galaxies [PDF]

, 2017
We investigate the environmental quenching of galaxies, especially those with stellar masses (M*)$10^{10.5} M_\odot$) within a redshift range. At a given redshift and M*, the environmental quenching effect is considered to be observed if the $d_{proj ...

Modeling Galactic Conformity with the Color-Halo Age Relation in the Illustris Simulation [PDF]

, 2015
Comparisons between observational surveys and galaxy formation models find that the mass of dark matter haloes can largely explain galaxies' stellar mass.

Bursting and quenching in satellite galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT 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 with the galics 2.0 semi-analytic model of galaxy formation.

A Stellar Mass Threshold for Quenching of Field Galaxies

, 2012
We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (

Recently Quenched Galaxies at z = 0.2 - 4.8 in the COSMOS UltraVISTA Field

, 2017
We present a new analysis of the stellar mass function and morphology of recently-quenched galaxies (RQGs), whose star formation has been recently quenched for some reason.

Star formation quenching in galaxies [PDF]

SCIENTIA SINICA Physica, Mechanica & Astronomica, 2017
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 the past $\sim10$ Gyr. As a result, the present day universe does not contain many star-bursting galaxies, which were the dominating population at $z\sim2$

Galaxy bulges and their black holes: a requirement for the quenching of star formation

, 2008
One of the central features of the last 8 to 10 billion years of cosmic history has been the emergence of a well-populated red sequence of non-star-forming galaxies.

Identifying and Distinguishing Quenching Galaxies with Spatially Resolved Star Formation in TNG50

The Astrophysical Journal
Using the TNG50 simulation, we determine observationally motivated metrics that can distinguish quenching galaxies from star-forming galaxies for M _* ≥ 10 ^9.5 M _⊙ , based on the spatial distribution of their stellar populations. Quenching galaxies are
