An Atlas of Color-selected Quiescent Galaxies at z > 3 in Public JWST Fields [PDF]
Astrophysical Journal, 2023 We present the results of a systematic search for candidate quiescent galaxies in the distant universe in 11 JWST fields with publicly available observations collected during the first 3 months of operations and covering an effective sky area of ∼145 ...

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.

Active Galactic Nucleus Quenching in Simulated Dwarf Galaxies
The Astrophysical Journal, 2023 We examine the quenching characteristics of 328 isolated dwarf galaxies $\left({10}^{8}\lt {M}_{\mathrm{star}}/{M}_{\odot }\lt {10}^{10}\right)$ within the Romulus25 cosmological hydrodynamic simulation.

THE QUENCHING TIMESCALE AND QUENCHING RATE OF GALAXIES
The Astrophysical Journal, 2016 ABSTRACT The average star formation rate (SFR) in galaxies has been declining since the redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the quenching process: the quenching timescale and the quenching rate among galaxies.

The size evolution of star-forming and quenched galaxies in the IllustrisTNG simulation [PDF]
, 2017 We analyze scaling relations and evolution histories of galaxy sizes in TNG100, part of the IllustrisTNG simulation suite. Observational qualitative trends of size with stellar mass, star-formation rate and redshift are reproduced, and a quantitative ...

Extreme Circumgalactic H i and C iii Absorption around the Most Massive, Quenched Galaxies [PDF]
Astrophysical Journal, 2018 Luminous red galaxies (LRGs) are the most massive galaxies at z ∼ 0.5 and, by selection, have negligible star formation (SF). These objects have halo masses between those of L* galaxies, whose circumgalactic media (CGMs) are observed to have large masses

A fast-rotator post-starburst galaxy quenched by supermassive black-hole feedback at z = 3 [PDF]
Nature Astronomy, 2023 The most massive galaxies in the Universe stopped forming stars due to the time-integrated feedback from central supermassive black holes (SMBHs). However, the exact quenching mechanism is not yet understood, because local massive galaxies were quenched ...

The Astrophysical Journal Letters, 2023 How passive galaxies form, and the physical mechanisms which prevent star formation over long timescales, are some of the most outstanding questions in understanding galaxy evolution.

The diverse star formation histories of early massive, quenched galaxies in modern galaxy formation simulations [PDF]
Monthly notices of the Royal Astronomical SocietyWe present a comprehensive study of the star formation histories of massive-quenched galaxies at z = 3 in three semi-analytic models (Shark, gaea, Galform) and three cosmological hydrodynamical simulations (Eagle, IllustrisTNG, Simba).
