Optical and HI data of 6 southern galaxy groups
Multi-wavelength observations of Hickson's Compact Groups (HCGs) have shown that many of these groups are physical bound structures and are in different stage of evolution, from... -
Stellar populations of CL 0048-2942
We present a detailed study of the cluster CL 0048-2942, located at z~0.64, based on a photometric and spectroscopic catalogue of 54 galaxies in a 5x5arcmin^2^ region centred in... -
Deep cluster survey in Chandra archival data
I present the first results of a search for clusters of galaxies in Chandra ACIS pointed observations at high galactic latitude with exposure times larger than 10ks. The survey... -
Baryon content of groups and clusters
We have analyzed the properties of a sample of 33 groups and clusters of galaxies for which both optical and X-ray data were available in the literature. This sample was built... -
Galaxy clusters {sigma}-T relationship
This is a sample of 149 galaxy clusters for which both the X-ray determined temperature T of the intracluster gas and the optical measured velocity dispersion {sigma} of the... -
Shape and orientation of superclusters
We present a study of the shape, size, and spatial orientation of superclusters of galaxies. Approximating superclusters by triaxial ellipsoids we show that superclusters are... -
The BAX Database
We present BAX, Base de Donnees Amas de Galaxies X (http://bax.ast.obs-mip.fr), a multi-wavelength database dedicated to X-ray clusters and groups of galaxies allowing detailed... -
Radio relics in LoTSS-DR2 and PSZ2
It is well-established that shock waves in the intracluster medium launched by galaxy cluster mergers can produce synchrotron emission, which is visible to us at radio... -
Early-type galaxies in the Centaurus cluster
We analyse the properties of the early-type dwarf galaxy population in the Centaurus cluster. We investigate the galaxy luminosity function, galaxy scaling relations down to... -
WINGS spectroscopy of 48 galaxy clusters
We present the results from a comprehensive spectroscopic survey of the WINGS (WIde-field Nearby Galaxy-cluster Survey) clusters, a program called WINGS-SPE. The WINGS-SPE... -
Redshifts of five EIS clusters
We report the results of the first multi-object spectroscopic observations at the Danish 1.54m telescope at La Silla, Chile. Observations of five cluster candidates from The ESO... -
Surface photometry in 7 nearby clusters
This is the first paper of a series investigating the scaling relations of early-type galaxies in clusters. Here we illustrate the multi-band imagery and the image reduction and... -
13 and 22cm radio flux from A3571
In this paper we report and discuss the results of a radio survey in the A3571 cluster complex, a structure located in the Shapley Concentration core, and formed by the three... -
GALEX Ultraviolet Virgo Cluster Survey (GUViCS)
The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering ~40 sq. deg in the far UV (FUV, {lambda}eff=1539{AA},...
