We carried out the deep spectroscopic observations of the nearby cluster A2151 with AF2/WYFFOS@WHT. The caustic technique enables us to identify 360 members brighter than $M_r = -16$ and within 1.3$R_{200}$. We separated the members into subsamples according to photometrical and dynamical properties such as colour, local environment and infall time. The completeness of the catalogue and our large sample allow us to analyse the velocity dispersion and the luminosity functions of the identified… 

Star formation in low-redshift cluster dwarf galaxies

Evolution of galaxies in dense environments can be affected by close encounters with neighbouring galaxies and interactions with the intracluster medium. Dwarf galaxies (dGs) are important as their

Infalling groups and galaxy transformations in the cluster A2142

We study galaxy populations and search for possible merging substructures in the rich galaxy cluster A2142. Normal mixture modelling revealed in A2142 several infalling galaxy groups and subclusters.

Studying star forming dwarf galaxies in Abell 779, Abell 1367, Coma, and Hercules clusters

Context. We continue to study star formation in dwarf galaxies located in nearby clusters. Aims. Known physical and chemical relations outlining the formation and evolution of dwarfs is compared in

NoSOCS in SDSS – VI. The environmental dependence of AGN in clusters and field in the local Universe

We investigated the variation in the fraction of optical active galactic nuclei (AGN) hosts with stellar mass, as well as their local and global environments. Our sample is composed of cluster

Fossil group origins: VIII RXJ075243.6+455653 a transitionary fossil group

It is thought that fossil systems are relics of structure formation in the primitive Universe. They are galaxy aggregations that have assembled their mass at high redshift with few or no subsequent

Supercluster A2142 and collapse in action: infalling and merging groups and galaxy transformations

Context. Superclusters with collapsing cores represent dynamically evolving environments for galaxies, galaxy groups, and clusters.Aims. We study the dynamical state and properties of galaxies and

The evolution of the luminosity function faint end of cluster galaxies in the Cluster-EAGLE simulation

Abstract In the last decade observations have been able to probe the evolution of the galaxy luminosity function, in particular showing a variation of its faint-end with redshift. We employ the data

Prospects for gamma-ray observations of Hercules cluster

Galaxy clusters (GCs) are the largest and most massive gravitationally bound objects in the large-scale structure of the Universe. Due to keV temperatures of virialized gas in the intracluster medium

The Hercules cluster in X-rays with XMM-Newton and Chandra

We present a detailed X-ray study of the central subcluster of the nearby ($z$ $\sim$0.0368) Hercules cluster (Abell 2151) identified as A2151C that shows a bimodal structure. A bright clump of hot

Deep spectroscopy in nearby galaxy clusters – V. The Perseus cluster

Dwarfs are the largest population of galaxies in number in the nearby Universe. Deep spectroscopic data are still missing to obtain a better understanding of their formation and evolution




We present the galaxy luminosity function (LF) of the Abell 119 cluster down to mag based on deep images in the u, g, and r bands taken by using MOSAIC II CCD mounted on the Blanco 4 m telescope at

The V-band luminosity function of galaxies in A2151

We present a wide field V-band imaging survey of approximately 1 deg 2 (∼7.2 h −2 75 Mpc 2 ) in the direction of the nearby cluster of galaxies Abell 2151 (the Hercules Cluster). The data are used to

The Luminosity Function of Low-Redshift Abell Galaxy Clusters

We present the results from a survey of 57 low-redshift Abell galaxy clusters to study the radial dependence of the luminosity function (LF). The dynamical radius of each cluster, r200, was estimated

We analyze the Luminosity Functions (LFs) of a subsample of 69 clusters from the RASS-SDSS galaxy cluster catalog. When calculated within the cluster physical sizes, given by r 200 or r 500 , all the

Galaxy luminosity functions in WINGS clusters

Aims. Using V band photometry of the WINGS survey, we derive galaxy luminosity functions (LF) in nearby clusters. This sample is complete down to MV =−15.15, and it is homogeneous, thus allowing the
