Mini-Quenching of z = 4 − 8 Galaxies by Bursty Star Formation [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The recent reported discovery of a low-mass z = 5.2 and an intermediate-mass z = 7.3 quenched galaxy with JWST/NIRSpec is the first evidence of halted star formation above z ≈ 5.

What drives galaxy quenching? A deep connection between galaxy kinematics and quenching in the local Universe [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We develop a 2D inclined rotating disc model, which we apply to the stellar velocity maps of 1862 galaxies taken from the MaNGA survey (SDSS public Data Release 15) . We use a random forest classifier to identify the kinematic parameters that are most connected to galaxy quenching.

High-velocity outflows persist up to 1 Gyr after a starburst in recently-quenched galaxies at z > 1 [PDF]
Monthly notices of the Royal Astronomical SocietyHigh-velocity outflows are ubiquitous in star-forming galaxies at cosmic noon, but are not as common in passive galaxies at the same epoch. Using optical spectra of galaxies selected from the UKIDSS Ultra Deep Survey (UDS) at z > 1, we perform a ...

Massive Quenched Galaxies at z ∼ 0.7 Retain Large Molecular Gas Reservoirs [PDF]
, 2017 The physical mechanisms that quench star formation, turning blue star-forming galaxies into red quiescent galaxies, remain unclear. In this Letter, we investigate the role of gas supply in suppressing star formation by studying the molecular gas content ...

The First Quiescent Galaxies in TNG300 [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We identify the first quiescent galaxies in TNG300, the largest volume of the IllustrisTNG cosmological simulation suite, and explore their quenching processes and time evolution to z = 0. We find that the first quiescent galaxies with stellar masses M*

ELVES. III. Environmental Quenching by Milky Way–mass Hosts
The Astrophysical Journal, 2023 Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way–mass groups.
