Widespread Rapid Quenching at Cosmic Noon Revealed by JWST Deep Spectroscopy

The Astrophysical Journal
Massive quiescent galaxies in the young Universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical mechanism drives rapid quenching. We study 14 massive quiescent galaxies ( $\

Magnetization of the IGM by Starburst Dwarf Galaxies?

, 2011
It is well known that the intergalactic or intracluster medium (IGM, ICM) is pervaded by a weak magnetic field, along with a population of relativistic particles.

Quenching through Tidal Gas Removal: Molecular Gas and Star Formation in Tidal Tails of z ∼ 0.7 Post-starburst Galaxies

The Astrophysical Journal
The active suppression of star formation in galaxies is critical for preventing the growth of overly massive systems and explaining the formation of present-day elliptical galaxies.

Molecular Gas Excitation in z ∼ 0.7 Gas-rich Poststarburst Galaxies from SQuIGG E

The Astrophysical Journal
Many poststarburst galaxies at z  ∼ 0.7 have been shown to retain substantial molecular gas reservoirs yet host low ongoing star formation, suggesting that the remaining gas may be inefficient at forming stars during the early postburst phase. We present

Simulating High-redshift Galaxies: Enhancing UV Luminosity with Star Formation Efficiency and a Top-heavy IMF

The Astrophysical Journal
Recent findings from photometric and spectroscopic JWST surveys have identified examples of high-redshift galaxies at z  ≳ 10. These high- z galaxies appear to form much earlier and exhibit greater UV luminosity than predicted by theoretical work.

Dead or Alive? How Bursty Star Formation and Patchy Dust Can Cause Temporary Quiescence in High-redshift Galaxies

The Astrophysical Journal
The recent discovery of a galaxy at z = 7.3 with undetected optical emission lines and a blue UV-to-optical continuum ratio in JWST spectroscopy is surprising and needs to be explained physically.

A Census of Quiescent Galaxies across 0.5 < z < 8 with JWST/MIRI: Mass-dependent Number Density Evolution of Quiescent Galaxies in the Early Universe

The Astrophysical Journal Letters
Recent JWST observations have revealed a large population of quiescent galaxies (QGs) at high redshift ( z  ∼ 4–8), challenging current models of early galaxy formation and quenching. Accurate number density estimates are crucial but remain uncertain. We

A Post-Starburst Pathway to Forming Massive Galaxies and Their Black Holes at z>6

International audienceUnderstanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires an understanding of how stellar mass grows in the host galaxies.
