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 ...

Post-starburst Galaxies in the Centers of Intermediate-redshift Clusters [PDF]
Astrophysical Journal, 2022 We present results from MUSE spatially resolved spectroscopy of 21 post-starburst galaxies in the centers of eight clusters from z ∼ 0.3 to z ∼ 0.4. We measure spatially resolved star formation histories (SFHs), the time since quenching (t Q ), and the ...

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.

The total infrared luminosity may significantly overestimate the star formation rate of quenching and recently quenched galaxies [PDF]
, 2014 The total infrared (IR) luminosity is very useful for estimating the star formation rate (SFR) of galaxies, but converting the IR luminosity into an SFR relies on assumptions that do not hold for all galaxies.

The Compact Structures of Massive z ∼ 0.7 Post-starburst Galaxies in the SQuIGGL⃗E Sample [PDF]
, 2022 We present structural measurements of 145 spectroscopically selected intermediate-redshift (z ∼ 0.7), massive (M ⋆ ∼ 1011 M ⊙) post-starburst galaxies from the SQuIGGL⃗E sample measured using wide-depth Hyper Suprime-Cam i-band imaging. This deep imaging

HST/WFC3 NEAR-INFRARED SPECTROSCOPY OF QUENCHED GALAXIES AT z ∼ 1.5 FROM THE WISP SURVEY: STELLAR POPULATION PROPERTIES [PDF]
, 2013 We combine Hubble Space Telescope (HST) G102 and G141 near-IR (NIR) grism spectroscopy with HST/WFC3-UVIS, HST/WFC3-IR, and Spitzer/IRAC [3.6 μm] photometry to assemble a sample of massive (log (Mstar/M☉) ∼ 11.0) and quenched (specific star formation ...

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 $z\sim2$
