Galaxy Quenching at the High Redshift Frontier: A Fundamental Test of Cosmological Models in the Early Universe with JWST-CEERS [PDF]

open access: yesThe Astrophysical Journal, 2023
We present an analysis of the quenching of star formation in massive galaxies ( M _* > 10 ^9.5 M _⊙ ) within the first 0.5–3 Gyr of the Universe’s history utilizing JWST-CEERS data.

Galaxy Quenching from Cosmic Web Detachment [PDF]

open access: yesThe Open Journal of Astrophysics, 2019
We propose the Cosmic Web Detachment (CWD) model, a framework to interpret the star-formation history of galaxies in a cosmological context. The CWD model unifies several starvation mechanisms known to disrupt or stop star formation into one single ...

MOSFIRE Spectroscopy of Quiescent Galaxies at 1.5 < z < 2.5. II - Star Formation Histories and Galaxy Quenching [PDF]

open access: yesAstrophysical Journal, 2019
We investigate the stellar populations for a sample of 24 quiescent galaxies at 1.5 < z < 2.5 using deep rest-frame optical spectra obtained with Keck MOSFIRE. By fitting templates simultaneously to the spectroscopic and photometric data, and exploring a

The Astrid Simulation: Evolution of Black Holes and Galaxies to z = 0.5 and Different Evolution Pathways for Galaxy Quenching

open access: yesThe Astrophysical Journal
We present new results from the ASTRID simulation from z = 3 to z = 0.5, covering the epoch of cosmic noon. The galaxy stellar mass function, as well as the black hole mass and luminosity functions in ASTRID , exhibit good agreement with recent ...

Photometric Objects Around Cosmic Webs (PAC). VII. Disentangling Mass and Environment Quenching with the Aid of Galaxy–Halo Connection in Simulations [PDF]

open access: greenThe Astrophysical Journal
Star formation quenching in galaxies plays a crucial role in galaxy evolution and is believed to be driven primarily by galaxy mass and environment.

Effect of local environment and stellar mass on galaxy quenching and morphology at $0.5 [PDF]

open access: yes, 2017
We study galactic star-formation activity as a function of environment and stellar mass over 0.5 0.5 it depends on galaxy stellar mass, demonstrating that the effects of quenching related to (stellar) mass and environment are not separable.

Mapping stellar content to dark matter halos. II. Halo mass is the main driver of galaxy quenching [PDF]

open access: yes, 2015
We develop a simple yet comprehensive method to distinguish the underlying drivers of galaxy quenching, using the clustering and galaxy-galaxy lensing of red and blue galaxies in SDSS.

Two Conditions for Galaxy Quenching: Compact Centres and Massive Haloes [PDF]

open access: yes, 2015
We investigate the roles of two classes of quenching mechanisms for central and satellite galaxies in the SDSS ($z 10^{11.8}M_{\odot}$ are dense ($\Sigma_{\rm 1kpc} > 10^{9}~ M_{\odot} {\rm kpc}^{-2}$), suggesting compaction-related quenching maintained ...

Galaxy evolution in the post-merger regime. II -- Post-merger quenching peaks within 500 Myr of coalescence

open access: yesThe Open Journal of Astrophysics
Mechanisms for quenching star formation in galaxies remain hotly debated, with galaxy mergers an oft-proposed pathway. In Ellison et al. (2022) we tested this scenario by quantifying the fraction of recently and rapidly quenched post-starbursts (PSBs) in

CONFRONTING MODELS OF DWARF GALAXY QUENCHING WITH OBSERVATIONS OF THE LOCAL GROUP [PDF]

open access: bronze, 2013
A number of mechanisms have been proposed to connect star-forming dwarf irregular galaxies with the formation of non-star-forming dwarf spheroidal galaxies (dSphs), but distinguishing between these mechanisms has been difficult. We use the Via Lactea (VL)
