The SAGA Survey. V. Modeling Satellite Systems around Milky Way–Mass Galaxies with Updated UniverseMachine

The Astrophysical Journal
Environment plays a critical role in shaping the assembly of low-mass galaxies. Here, we use the U niverse M achine (UM) galaxy–halo connection framework and Data Release 3 of the Satellites Around Galactic Analogs (SAGA) Survey to place dwarf galaxy ...

GLACE survey: OSIRIS/GTC multi-object spectroscopy of the rich galaxy cluster ZwCl 0024.0+1652 at

Context. Galaxy clusters are among the largest and densest structures in the Universe. Their high density generally increases the suppression of star formation, known as quenching, altering galaxy properties. Aims. We study the quenching of emission-line

Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel

The Astrophysical Journal
The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

The inside-out quenching of the MHONGOOSE galaxy NGC 1371 [PDF]

We present the deepest 21 cm spectral line and 1.4 GHz broad-band continuum observations of nearby early-type spiral galaxy NGC 1371 as part of the MeerKAT H i Observations of Nearby Galactic Objects: Observing Southern Emitters (MHONGOOSE) survey.

The Structure and Formation Histories of Low-mass Quiescent Galaxies in the A2744 Cluster Environment

The Astrophysical Journal
Low-mass quiescent galaxies are thought to predominantly reside in overdense regions, as environmental effects are often invoked to explain their shutdown of star formation. These longer-timescale quenching mechanisms—such as interactions with hot gas in

AGN Host Galaxy Properties and Mass Function

, 2016
Supermassive black hole growth, nuclear activity, and galaxy evolution have been found to be closely related. In the context of AGN-galaxy coevolution, I will discuss about the relation found between the host galaxy properties and the central BH and I ...

Searching within Galaxies for the Earliest Signs of Quenching With Spatially Resolved Star Formation Histories in UVCANDELS Galaxies at z < 0.3

The Astrophysical Journal
Understanding the complicated processes that regulate star formation and cause a galaxy to become quiescent is key to our comprehension of galaxy evolution.

Star formation and quenching in galaxy formation models [PDF]

, 2019
Galaxies locally have been observed to have a bimodal distribution for many properties, such as colour, star formation rate and morphology. These properties can be used to separate galaxies into two classes - the 'blue cloud' and the 'red sequence ...

On the Origin of Quenched but Gas-rich Regions at Kiloparsec Scales in Nearby Galaxies

The Astrophysical Journal
We use resolved spectroscopy from MaNGA to investigate the significance of both local and global properties of galaxies to the cessation of star formation at kpc scales.

Resolved Maps of Gas and Dust in a Massive Quiescent Galaxy at z = 2 from INQUEST-JWST: Evidence of Accretion and Rejuvenation

The Astrophysical Journal
Quiescent galaxies in the distant Universe exhibit a range of gas content that may indicate a variety of quenching processes are at play. Mapping the distribution and kinematics of the gas can illuminate its origins, but nearly all such observations have
