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

The 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 ...

LoCuSS : pre-processing in galaxy groups falling into massive galaxy clusters at z=0.2 [PDF]

, 2017
We report direct evidence of pre-processing of the galaxies residing in galaxy groups falling into galaxy clusters drawn from the Local Cluster Substructure Survey (LoCuSS). 34 groups have been identified via their X-ray emission in the infall regions of

Structural properties of central galaxies in groups and clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2009
Using a statistically representative sample of 911 central galaxies (CENs) from the Sloan Digital Sky Survey (SDSS) Data Release 4 group catalogue, we study how the structure (shape and size) of the first rank (by stellar mass) group and cluster members depends on (1) galaxy stellar mass (Mstar), (2) the global environment defined by the dark matter ...

European Journal of Heart Failure consensus statement. Heart failure pharmacotherapy for patients with heart failure with reduced ejection fraction and concomitant atrial fibrillation: Review of evidence and call to action

European Journal of Heart Failure, EarlyView.
Heart failure (HF) and atrial fibrillation (AF) are major global health challenges with rising prevalence and significant morbidity, mortality, and healthcare burden. Despite advances in HF management, AF remains a critical comorbidity that worsens outcomes and requires ad hoc treatment strategies, increasing the risk of non‐adherence and side effects.

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

The 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.

Cosmological Simulations of Galaxy Groups and Clusters. III. Constraining Quasar Feedback Models with the Atacama Large Millimeter Array

The Astrophysical Journal, 2023
The thermal Sunyaev–Zeldovich (SZ) effect serves as a direct potential probe of the energetic outflows from quasars that are responsible for heating the intergalactic medium.

A SYSTEMATIC SEARCH FOR X-RAY CAVITIES IN GALAXY CLUSTERS, GROUPS, AND ELLIPTICAL GALAXIES [PDF]

, 2016
We perform a comprehensive study of X-ray cavities using a large sample of X-ray targets selected from the Chandra archive. The sample is selected to cover a large dynamic range including galaxy clusters, groups, and individual galaxies. Using β-modeling

Disruption of satellite galaxies in simulated groups and clusters: the roles of accretion time, baryons, and pre-processing [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We investigate the disruption of group and cluster satellite galaxies with total mass (dark matter plus baryons) above 1010M⊙ in the Hydrangea simulations, a suite of 24 high-resolution cosmological hydrodynamical zoom-in simulations based on the EAGLE ...

NUMERICAL ESTIMATOR FOR LARGE-SCALE COSMIC STRUCTURES

Odessa Astronomical Publications, 2018
Components of large-scale structure (LSS) of Universe includes galaxy clusters , walls , filaments , groups and field galaxies. The question of spatial organization of all these components remains open despite of a number of recently developed methods of

Clusters and groups of galaxies in the simulated local universe [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
We compare the properties of galaxy groups extracted from the Updated Zwicky Catalogue (UZC) with those of groups extracted from N-body simulations of the local Universe, in a LambdaCDM and a tauCDM cosmology. In the simulations, the initial conditions of the dark matter density field are set to reproduce the present time distribution of the galaxies ...
