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…
The Substructure-Alignment Connection
Manolis Plionis, Spyros Basilakos
Using a sample of 903 APM clusters we investigate whether their dynamical status, as evidenced by the presence of significant substructures, is related to the large-scale structure…
Testing for substructure in optical and X-ray clusters
Vaggelis Kolokotronis, Spyros Basilakos, Manolis Plionis +1
We present a detailed study of the morphological features of 22 rich galaxy clusters. We systematically compare cluster images and morphological parameters in an attempt to reliabl…
Galaxy Cluster Shapes
Spyros Basilakos, Manolis Plionis, Steve Maddox
We estimate the distribution of intrinsic shapes of the APM galaxy clusters from their corresponding distribution of projected shapes. We smooth the discrete galaxy distribution an…
