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 construct the luminosity function (LF) down to MV ≈− 14.85, thus allowing us to study the dwarf galaxy population in A2151 for the first time. The obtained global LF is well described by a Schechter function with best-fit parameters α = −1.29 +0.09 −0.08 and M ∗ V = −21.41 +0.44 −0.41 . The radial… 

Deep spectroscopic luminosity function of Abell 85: no evidence for a steep upturn of the faint-end slope

We present a new deep determination of the spectroscopic luminosity function (LF) within the virial radius of the nearby and massive Abell 85 (A85) cluster down to the dwarf regime (M* + 6) using

Luminosity segregation in three clusters of galaxies (A119, A2443, A2218)

We use deep wide-field V-band imaging obtained with the Wide Field Camera at the prime focus of the Issac Newton Telescope to study the spatial and luminosity distribution of galaxies in three low

The Luminosity Function of Nearby Galaxy Clusters. I. A Catalog of Galaxies Within the Central 0.83 Square Degrees of the Centaurus Cluster

We present a catalog of all galaxies with V ≤ 22.0 and Riso > 3′′ within a 0.83 deg2 region centered on the Centaurus Cluster (Abell 3526) at α = 12h48m, δ = -41°18′. V-band total magnitudes along

Deep spectroscopy of nearby galaxy clusters – II. The Hercules cluster

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


This paper presents the first results of an Hα imaging survey of galaxies in the central regions of the A2151 cluster. A total of 50 sources were detected in Hα, from which 41 were classified as

Hubble Space Telescope survey of the Perseus Cluster -III: The effect of local environment on dwarf galaxies

We present the results of a Hubble Space Telescope (HST) study of dwarf galaxies in the outer regions of the nearby rich Perseus cluster, down to M-V = -12, and compare these with the dwarf

A study of catalogued nearby galaxy clusters in the SDSS-DR4 - II. Cluster substructure

Context. According to the current cosmological paradigm, large scale structures form hierarchically in the Universe. Clusters of galaxies grow through a continuous accretion of mass, and the presence

A normal abundance of faint satellites in the fossil group NGC 6482

Fossil groups are considered the end product in a galaxy group's evolution -- a massive central galaxy that dominates the luminosity budget of the group, as the outcome of efficient merging between

Structural Parameters of Dwarf Galaxies in the Coma Cluster: On the Origin of dS0 Galaxies

In this paper we analyze the structural parameters of the dwarf galaxies in the Coma Cluster with -18 ≤ MB ≤ -16 and classify them into two types; those with surface brightness profiles well fitted

Fossil groups origins - I. RX J105453.3+552102 a very massive and relaxed system at z ~ 0.5

Context. The most accepted scenario for the origin of fossil groups is that they are galaxy associations in which the merging rate was fast and efficient. These systems have assembled half of their



The dwarf galaxy population in Abell 2218

We present results from a deep photometric study of the rich galaxy cluster Abell 2218 (z = 0.18) based on archival Hubble Space Telescope WFPC2 F606W images. These have been used to derive the

The dwarf LSB galaxy population of the Virgo cluster - I. The faint-end slope of the luminosity function

The widely varying dwarf galaxy counts in different environments provide a strong challenge to standard hierarchical clustering models. The luminosity function is not universal, but seems to be

U-, B- and r-band luminosity functions of galaxies in the Coma cluster
