ON THE DETERMINATION OF GALAXY STRUCTURE ELLIPTICITY

open access: yesOdessa Astronomical Publications, 2007
We discuss factors influencing the determination of the observed shape of galaxy clusters when the covariance ellipse method is involved. The analysis of 377 Abell clusters show that at greater distances from the cluster center the ellipticity is rather ...

Galaxy Superclusters Detected in the Modified PF-Catalog Using the FOF Method

open access: yesOpen Astronomy, 2011
The Modified Catalog of Galaxy Clusters and Groups (Panko & Flin 2006, PF), covering an area of 5000 square degrees in the southern sky, was used as the input for the search of galaxy superclusters.

On the Origin and Evolution of the Intra-Cluster Light: A Brief Review of the Most Recent Developments

open access: yesGalaxies, 2021
Not all the light in galaxy groups and clusters comes from stars that are bound to galaxies. A significant fraction of it constitutes the so-called intracluster or diffuse light (ICL), a low surface brightness component of groups/clusters generally found

Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster

open access: yes, 2018
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a ...

Morphological Distribution of Galaxies in Some Nearby Clusters

open access: yesOpen Astronomy, 2019
We study the morphological distribution of galaxies in some nearby clusters, using the Sloan Digital Sky Survey – Data Release 9 (SDSS-DR9). The segregation between early-type galaxies and late-type ones is investigated in g – r / u – g color space ...

Unravelling the origin of large-scale magnetic fields in galaxy clusters and beyond through Faraday Rotation Measures with the SKA [PDF]

open access: yes, 2014
We investigate the possibility for the SKA to detect and study the magnetic fields in galaxy clusters and in the less dense environments surrounding them using Faraday Rotation Measures.

THE ORIENTATION OF GALAXIES IN GALAXY CLUSTERS [PDF]

open access: yesThe Astrophysical Journal, 2010
We present an analysis of the spatial orientations of galaxies in the 247 optically selected rich Abell clusters, having in the considered area at least 100 members. We investigated the relation between angles giving information about galaxy angular momenta and the number of members in each structure.

A catalog of Nearby Poor Clusters of Galaxies [PDF]

open access: yes, 1999
A catalog of 732 optically selected, nearby poor clusters of galaxies covering the entire sky north of $\rm -3^{\circ}$ declination is presented. The poor clusters, called WBL clusters, were identified as concentrations of 3 or more galaxies with ...
