A weak lensing analysis of the Abell 2163 cluster
M. Radovich, E. Puddu, A. Romano +2
Weak lensing analysis is applied to a deep, one square degree r-band CFHT-Megacam image of the Abell 2163 field. The observed shear is fitted with Single Isothermal Sphere and Nava…

Scaling relations of the colour-detected cluster RzCS 052 at z=1.016 and of some other high redshift clusters
S. Andreon, R. De Propris, E. Puddu +2
We report on the discovery of the z=1.016 cluster RzCS 052 using a modified red sequence method, followup spectroscopy and X-ray imaging. This cluster has a velocity dispersion of…

New evidence for a linear colour-magnitude relation and a single Schechter function for red galaxies in a nearby cluster of galaxies down to M*+8
S. Andreon, J. -C. Cuillandre, E. Puddu +1
The colour and luminosity distributions of red galaxies in the cluster Abell 1185 (z=0.0325) were studied down to M*+8 in the B, V and R bands. The colour-magnitude (hereafter CM)…
