Environmental quenching of high-redshift galaxies: Interpreting JWST observations with simulations

Astronomy & Astrophysics
Recent observations of the high-redshift Universe (z > 3), particularly with the James Webb Space Telescope (JWST), have revealed a population of quenched galaxies that challenges current galaxy formation models, which systematically underpredict their ...

Evidence for Inside-out Galaxy Growth and Quenching of a z ∼ 2 Compact Galaxy From High-resolution Molecular Gas Imaging

, 2019
We present high spatial resolution imaging of the CO(1–0) line from the Karl G. Jansky Very Large Array of COSMOS 27289, a massive, compact star-forming galaxy (SFG) at z = 2.234.

SDSS-C4 3028: the Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium

The Open Journal of Astrophysics
SDSS-C4 3028 is a galaxy cluster at $z=0.061$, notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent spectroscopically-confirmed member galaxies. From Subaru/HSC imaging, we derived a weak lensing mass of $

Environmental Quenching in the SAMI Galaxy Survey and Hydrodynamical Simulations

, 2023
In this thesis, we investigate the mechanisms that quench star formation in all environments and how fast the quenching processes happen, especially in dense regions like groups and clusters.

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 ( $\

A Massive Quiescent Galaxy in a Group Environment at z = 4.53

The Astrophysical Journal
We report on the spectroscopic confirmation of a massive quiescent galaxy at z _spec = 4.53 in the COSMOS field. The object was first identified as a galaxy with suppressed star formation at z _phot ∼ 4.65 from the COSMOS2020 catalog.

Star formation quenching precedes morphological transformation in COSMOS-Web’s richest galaxy groups

Astronomy & Astrophysics
We analyzed the 25 richest galaxy groups in COSMOS-Web across the redshift range z = 0.18–3.65, identified using the Adaptive Matched Identifier of Clustered Objects (AMICO) algorithm.

Investigating Galaxy Quenching with the SDSS: Stellar Metallicities as a Tracer of Quenching Mechanisms

, 2017
Peng et al. (2015, Nature, 521, 192) analysed stellar metallicities of 26,000 SDSS galaxies and found that galaxies with stellar masses below 1011 solar masses are primarily quenched due to the halting of the supply of cold gas (strangulation).

A Quenched and Relatively Isolated Dwarf Galaxy in the Local Volume

The Astrophysical Journal
An increasing number of discoveries of isolated and quenched dwarf galaxies are challenging the idea that the present-day local environment of low-mass systems is the main determinant of their quenching.
