No Evidence of Asymmetrically Enhanced Star Formation in Infalling Galaxies in UNIONS
The Astrophysical JournalRam pressure stripping is a well-known environmental quenching mechanism that removes gas from galaxies infalling into groups and clusters. In some extreme examples of ram pressure stripping, galaxies with extended gas tails show evidence of enhanced ...

Tracing the Formation History of Intrahalo Light with Horizon Run 5
The Astrophysical JournalWe investigate the formation history of intrahalo light (IHL) using the high-resolution (∼1 kpc), large-scale (∼1 Gpc) cosmological hydrodynamical simulation Horizon Run 5 (HR5).

THE ROLE OF POOR GALAXY CLUSTERS FOR STUDYING SUPERCLUSTER STRUCTURE
Odessa Astronomical Publications, 2008 The distribution of galaxy clusters is analyzed in regions of 6 galaxy superclusters with both measured and estimated redshifts. The positions of ACO and APM galaxy clusters in the regions are compared with the positions of galaxy clusters and groups ...

COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction
Astronomy & AstrophysicsAims. We investigate the redshift evolution and group richness dependence of the quiescent galaxy fraction and red sequence (RS) parameters in COSMOS galaxy groups, spanning a wide redshift range, from z = 0 to z = 3.7. Methods.

Cold Gas Infall onto a Brightest Group Galaxy via a Gas-rich Minor Merger
The Astrophysical Journal LettersDust and cold gas are not uncommon in nearby early-type galaxies (ETGs) and represent an important aspect of their evolution. However, their origin has been debated for decades.

The Astrophysical JournalThe tight relationship between the stellar mass and halo mass of galaxies is one of the most fundamental scaling relations in galaxy formation and evolution. It has become a critical constraint for galaxy formation models.

The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8
The Astrophysical JournalWe present results from a Keck/DEIMOS survey to study satellite quenching in group environments at z ~ 0.8 within the Extended Groth Strip (EGS). We target 11 groups in the EGS with extended X-ray emission. We obtain high-quality spectroscopic redshifts

Galaxy Superclusters and Their Complexes in the Cosmic Web
UniverseThe richest and largest structures in the cosmic web are galaxy superclusters, their complexes (associations of several almost connected very rich superclusters), and planes.
