The quenching time and timescale distribution of z~2 quiescent galaxies from precise colour distribution analysis

The Open Journal of Astrophysics
Understanding when and how galaxies quench their star formation is crucial for understanding the dominant physical processes at play. The spectral energy distribution (SED) of galaxies encodes significant information on their past histories: the relative

Star formation concentration as a tracer of environmental quenching in action: a study of the scp>eagle/scp> and scp>c-eagle/scp> simulations

, 2023
We study environmental quenching in the eagle/c-eagle cosmological hydrodynamic simulations over the last 11 Gyr (i.e. z = 0-2). The simulations are compared with observations from the SAMI Galaxy Survey at z = 0. We focus on satellite galaxies in galaxy

No Detectable One-halo Galactic Conformity Signal with Halo-mass Estimates Consistent with Weak-lensing Constraints

The Astrophysical Journal Letters
One-halo galactic conformity is the tendency for satellites in halos with quenched centrals to have lower star formation activity than those in halos with star-forming centrals at fixed halo mass.

Galaxy evolution near groups and clusters: ejected satellites and the spatial extent of environmental quenching

, 2013
Galaxies that are several virial radii beyond groups/clusters show preferentially quies-cent star formation rates. Using a galaxy group/cluster catalog from the Sloan Digital Sky Survey, together with a cosmological N-body simulation, we examine the ...

The Heavy Metal Survey: The Evolution of Stellar Metallicities, Abundance Ratios, and Ages of Massive Quiescent Galaxies since z ∼ 2

The Astrophysical Journal
We present the elemental abundances and ages of 19 massive quiescent galaxies at z ∼ 1.4 and z ∼ 2.1 from the Keck Heavy Metal Survey. The ultradeep LRIS and MOSFIRE spectra were modeled using a full-spectrum stellar population fitting code with variable

Modeling the Dependence of Galaxy Quenching on Stellar, Baryonic and Halo Mass in the ECO Survey

, 2023
Constraining the connection between the galaxy properties and the dark matter halos they reside in is a powerful tool for understanding the processes responsible for galaxy formation.

Astrophysical black holes: An explanation for the galaxy quenching

Journal of High Energy Astrophysics
In light of increasing observational evidence supporting the existence of ultra-compact objects, we adopt the term astrophysical black hole to refer to any object having a huge mass confined within a sufficiently small region of spacetime. This terminology encompasses both the classical black hole solutions predicted by general relativity, as well as ...

Clues to inside-out quenching in quiescent galaxies at 1.2 ≲ z ≲ 2.2: Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE

Astronomy & Astrophysics
Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into star-formation quenching and stellar mass assembly mechanisms.

The suppression of star formation and the effect of the galaxy environment in low-redshift galaxy groups

, 2012
Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use Galaxy Evolution Explorer imaging of a statistically representative sample of 23 galaxy groups at z ≈ 0.06 to

BEACON: JWST NIRCam Pure-parallel Imaging Survey. IV. A Systematic Search for Galaxy Overdensities and Evidence for Gas Accretion Mode Transition

The Astrophysical Journal
We systematically search for galaxy overdensities using 20 independent fields with a minimum of six filters (F090W, F115W, F150W, F277W, F356W, and F444W) from BEACON, the JWST Cycle 2 NIRCam pure-parallel imaging survey.
