Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts

Astronomy & Astrophysics
Context. The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these effects, particularly with respect to mechanisms such as quenching ...

A Full Active Galactic Nuclei Feedback Prescription for Numerical Models: Negative, Positive, and Hot Gas-ejection Modes

The Astrophysical Journal Supplement Series
We build upon the state-of-the-art semianalytic model FEGA24 for the formation and evolution of galaxies, which integrates the latest prescriptions relevant to galaxy formation and evolution, alongside a comprehensive active galactic nuclei (AGN ...

The Large-scale Structure Supplies the Formation of Gas-star Misaligned Galaxies

The Astrophysical Journal Letters
Using the integral field unit data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we build a sample of gas-star misaligned galaxies. The large-scale environment of misaligned galaxies is dominated by filaments and clusters, while it

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

The Astrophysical Journal
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.

The Route to Unveil the Cosmic Genealogy of Supermassive Black Hole Binaries Using Nanohertz Gravitational Waves and Galaxy Surveys

The Astrophysical Journal
The nanohertz stochastic gravitational wave background (SGWB), generated by unresolved supermassive black hole binaries (SMBHBs), provides a unique probe of their population and its cosmic evolution.

Evolution of clusters of galaxies

The Astrophysical Journal, 1991
In hierarchical models for structure formation like CDM, the mass scale of clustering evolves rapidly and clusters in the past are predicted to be less massive, but denser and more numerous. The indication from optical searches is that the cluster population is roughly stable in that high velocity dispersion clusters seem to be about as abundant at z ~

The JWST-SUSPENSE Ultradeep Spectroscopic Program: Survey Overview and Star Formation Histories of Quiescent Galaxies at 1 < z < 3

The Astrophysical Journal
We present an overview and first results from the Spectroscopic Ultradeep Survey Probing Extragalactic Near-infrared Stellar Emission (SUSPENSE), executed with NIRSpec on JWST.

On the Signature of Black Holes on the Quenched Stellar Mass Function

The Astrophysical Journal
As star-forming galaxies approach or exceed a stellar mass of around 10 ^11 M _⊙ , they are increasingly likely to be quenched in a process generically called mass quenching.

Emergence of the Galaxy Morphology–Star Formation Activity–Clustercentric Radius Relations in Galaxy Clusters

The Astrophysical Journal
We investigate when and how the relations of galaxy morphology and star-forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy clusters with total mass ${{M}}_{\mathrm{tot}}^{\mathrm{cl}}\gt 5\times {10}^{13}
