The aim of this review article is to give a comprehensive description of the scaling properties
detected for the distribution of cosmic structures, like galaxies and galaxy clusters. I will also …

We evaluate in a homogeneous way the optical masses of 170 nearby clusters (z≤ 0.15).
The sample includes both data from the literature and the new ESO Nearby Abell Clusters …

We present a detailed analysis of the surface brightness distribution of the brightest cluster
galaxy (BCG) in each of 24 galaxy clusters at 0.03< z< 0.13. We use two-dimensional profile …

We present an objective and automated procedure for detecting clusters of galaxies in
imaging galaxy surveys. Our Voronoi Galaxy Cluster Finder (VGCF) uses galaxy positions …

Using a large and well-controlled sample of clusters of galaxies, we investigate the relation
between cluster velocity dispersions and X-ray temperatures of intra-cluster gas. In order to …

We investigate the magnitude and internal alignment of the angular momentum of cold dark
matter haloes in simulations with and without baryons. We analyse the cumulative angular …

We have determined the radial velocity-dispersion profiles (VDps) of 72 clusters, each with
over 50 confirmed members. The velocity dispersion σv in clusters is found to be a strong …

We study the size and shape of low-density regions in the local Universe, which we identify
in the smoothed density field of the PSCz flux-limited IRAS galaxy catalogue. After …

We measure the ellipticity of isolated clusters of galaxies in the Sloan Digital Sky Survey
(SDSS) using gravitational lensing. We stack the clusters, rotating so that the major axes of …

We construct a photometric catalogue of very faint galaxies (I≲ 25.5) using deep CCD
images taken with the 4.2-m William Herschel telescope of fields centred on two distant X …
