Decoding the Single-peaked H i Spectra of Low Redshift Poststarburst Galaxies
The Astrophysical JournalRecent observations with the Five-hundred-meter Aperture Spherical Telescope have revealed abundant reservoirs of neutral hydrogen (H I ) in low-redshift poststarburst galaxies (PSBs), raising the question of why star formation ceases rapidly in these ...

Astronomy & AstrophysicsContext. Galaxies may suffer some starburst and quenched periods in their history due to galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (EoR) do not accurately model the effects of the star formation history

The Origin of [OII] Emission in Recently Quenched AGN Hosts
, 2010 We have employed emission-line diagnostics derived from DEIMOS and NIRSPEC spectroscopy to determine the origin of the [OII] emission line observed in six AGN hosts at z~0.9. These galaxies are a subsample of AGN hosts detected in the Cl1604 supercluster

Starbursts in interacting galaxies: Observations and models [PDF]
Starbursts have been a puzzling field of research for more than a decade. It is evident that they played a significant role in the evolution of many galaxies but still quite little is known about the starburst mechanisms.

The Open Journal of AstrophysicsWe investigate the effects of ram-pressure stripping on four galaxies within the massive, strong-lensing cluster MACS-J0138.0-2155 ($z=0.336$). Of these, three are classified as jellyfish galaxies, with significant elongated tails. Two of these jellyfish

The Astrophysical JournalJames Webb Space Telescope (JWST) has revealed temporarily quenched and ultraviolet-luminous galaxies in the early Universe, suggesting enhanced star formation stochasticity. Verifying this hypothesis is critical yet challenging.

Widespread Rapid Quenching at Cosmic Noon Revealed by JWST Deep Spectroscopy
The Astrophysical JournalMassive 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 ( $\
