The Cluster M/L and the Value of Omega_m
H. Andernach, M. Plionis, O. L'opez-Cruz +2
From an up-to-date compilation of ACO cluster redshifts and velocity dispersions we extract a homogeneous sample of 459 clusters with robust velocity dispersion. Using the virial t…
The Richness-Shape Relation of the 2dFGRS Groups
Manolis Plionis, Spyros Basilakos
We estimate the group shape of the recently compiled Pecolation-Inferred Galaxy Group (2PIGG) catalogue. Using a set of integral equations we invert the projected distribution of g…
The XMM-2df Cluster Survey
T. Gaga, M. Plionis, I. Georgantopoulos +5
We present the results from a shallow (2-10 ksec) XMM/2dF survey. Our survey covers 18 XMM fields () previously spectroscopically followed up with the Anglo-Aus…
Comparison between optical and X-ray cluster detection methods
S. Basilakos, M. Plionis, S. Georgakakis +4
In this work we present combined optical and X-ray cluster detection methods in an area near the North Galactic Pole area, previously covered by the SDSS and 2dF optical surveys. T…
