Galaxies in Clusters: the Observational Characteristics of Bow-Shocks, Wakes and Tails [PDF]

open access: yes, 1999
The dynamical signatures of the interaction between galaxies in clusters and the intracluster medium (ICM) can potentially yield significant information about the structure and dynamical history of clusters.

Galaxy Populations in Groups and Clusters: Evidence for a Characteristic Stellar Mass Scale at M ∗ ∼ 109.5 M ⊙

open access: yesThe Astrophysical Journal, 2023
We use the DR9 of the DESI legacy imaging survey and SDSS galaxy groups to measure the conditional luminosity function (CLF) for groups with halo mass M _h ≥ 10 ^12 M _⊙ and redshift 0.01 ≤ z ≤ 0.08, down to a limiting r -band magnitude of M _r = −10 to −

The HI content of the Eridanus group of galaxies [PDF]

open access: yes, 2004
The HI content of galaxies in the Eridanus group is studied using the GMRT observations and the HIPASS data. A significant HI deficiency up to a factor of 2-3 is observed in galaxies in the high galaxy density regions.

A New X-ray Selected Sample of Very Extended Galaxy Groups from the ROSAT All-Sky Survey

open access: yes, 2018
Some indications for tension have long been identified between cosmological constraints obtained from galaxy clusters and primary CMB measurements.

Gas-rich, Field Ultra-diffuse Galaxies Host Few Gobular Clusters

open access: yesThe Astrophysical Journal Letters, 2022
We present Hubble Space Telescope imaging of 14 gas-rich, low-surface-brightness galaxies in the field at distances of 25–36 Mpc, with mean effective radii and g -band central surface brightnesses of 1.9 kpc and 24.2 mag arcsec ^−2 .

X-ray bright groups and their galaxies [PDF]

open access: yes, 2002
Combining X-ray data from the ROSAT PSPC and optical data drawn from the literature, we examine in detail the relationship between the X-ray and optical properties of X-ray bright galaxy groups. We find a relationship between optical luminosity and X-ray

Test of Cosmic Web-feeding Model for Star Formation in Galaxy Clusters in the COSMOS Field

open access: yesThe Astrophysical Journal
It is yet to be understood how large-scale environments influence star formation activity in galaxy clusters. One recently proposed mechanism is that galaxy clusters can remain star forming when fed by infalling groups and star-forming galaxies from ...

The Blooming Tree Algorithm at Work: Clusters, Filaments, and Superclusters in the Field of A2029

open access: yesThe Astrophysical Journal
The Blooming Tree (BT) algorithm, based on the hierarchical clustering method, is designed to identify clusters, groups, and substructures from galaxy redshift surveys.
