Large scale structure in the HI Parkes All-Sky Survey: Filling the Voids with HI galaxies?
S. Basilakos, M. Plionis, K. Kovac +1
We estimate the two-point correlation function in redshift space of the recently compiled HIPASS neutral hydrogen (HI) sources catalogue, which if modeled as a power law, $ξ(r)=(r_…
Environmental Influences on the Morphology and Dynamics of Group Size Haloes
Cinthia Ragone-Figueroa, Manolis Plionis
We use group size haloes identified with a ``friends of friends'' (FOF) algorithm in a concordance GADGET2 (dark matter only) simulation to investigate the dependence o…
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…
