MOSFIRE Spectroscopy of Quiescent Galaxies at 1.5 < z < 2.5. II - Star Formation Histories and Galaxy Quenching [PDF]
, 2019 We investigate the stellar populations for a sample of 24 quiescent galaxies at 1.5 < z < 2.5 using deep rest-frame optical spectra obtained with Keck MOSFIRE. By fitting templates simultaneously to the spectroscopic and photometric data, and exploring a

What has quenched the massive spiral galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 ABSTRACT Quenched massive spiral galaxies have attracted great attention recently, as more data are available to constrain their environment and cold gas content. However, the quenching mechanism is still uncertain, as it depends on the mass range and baryon budget of the galaxy.

Gone after one orbit: How cluster environments quench galaxies [PDF]
, 2019 The effect of galactic orbits on a galaxy's internal evolution within a galaxy cluster environment has been the focus of heated debate in recent years.

The Astrophysical Journal, 2023 We use the spectral energy distribution fitting code Prospector to reconstruct the nonparametric star formation history (SFH) of massive ( $\mathrm{log}{M}_{* }\gt 10.3$ ) star-forming galaxies (SFGs) and quiescent galaxies (QGs) at redshift z _obs ∼ 2 ...

How is star formation quenched in massive galaxies? [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 The bimodality in observed present-day galaxy colours has long been a challenge for hierarchical galaxy formation models, as it requires some physical process to quench (and keep quenched) star formation in massive galaxies. Here we examine phenomenological models of quenching by post-processing the star formation histories of galaxies from ...

The Astrophysical Journal, 2023 We investigate the relationship between environment, morphology, and the star formation rate (SFR)–stellar mass relation derived from a sample of star-forming (SF) galaxies (commonly referred to as the “star formation main sequence”, SFMS) in the COSMOS ...

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 $z\sim2$

On the Signature of Black Holes on the Quenched Stellar Mass Function
The Astrophysical JournalAs star-forming galaxies approach or exceed a stellar mass of around 10 ^11 M _⊙ , they are increasingly likely to be quenched in a process generically called mass quenching.
