The Serendipitous XMM-Newton Cluster Athens Survey (SEXCLAS): Sample selection and the cluster log N - log S
V. Kolokotronis, A. Georgakakis, S. Basilakos +4
In this paper we serendipitously identify X-ray cluster candidates using XMM-Newton archival observations complemented by 5-band optical photometric follow-up observations (r~23 ma…
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 XMM/2dF survey III: Comparison between optical and X-ray cluster detection methods
S. Basilakos, M. Plionis, A. Georgakakis +4
We directly compare X-ray and optical techniques of cluster detection by combining SDSS photometric data with a wide-field ( deg) XMM-{\em Newton} survey in the Nor…
Supercluster Properties as a Cosmological Probe
V. Kolokotronis, S. Basilakos, M. Plionis
We investigate the supercluster shape properties of the all-sky observed (Abell/ACO) and simulated (Virgo data) cluster catalogues using an approach based on differential geometry.…
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…
Cosmological Constraints from the Clustering Properties of the X-Ray Brightest Abell-type Cluster Sample
S. Borgani, M. Plionis, E. Kolokotronis
We present an analysis of the 2-point correlation function, of the X-ray Brightest Abell-type Cluster sample (XBACs; Ebeling et al. 1998) and of the cosmological constraints that i…
