The dynamical state of RX J1347.5-1145 from a combined strong lensing and X-ray analysis
M. Miranda, M. Sereno, E. De Filippis +1
We perform a combined X-ray and strong lensing analysis of RX J1347.5-1145, one of the most luminous galaxy clusters at X-ray wavelengths. We show that evidence from strong lensing…
Steps toward a classifier for the Virtual Observatory. I. Classifying the SDSS photometric archive
R. D'Abrusco, A. Staiano, G. Longo +2
Modern photometric multiband digital surveys produce large amounts of data that, in order to be effectively exploited, need automatic tools capable to extract from photometric data…
Steps towards a map of the nearby universe
R. d'Abrusco, G. Longo, A. Staiano +3
We present a new analysis of the Sloan Digital Sky Survey data aimed at producing a detailed map of the nearby (z < 0.5) universe. Using neural networks trained on the available sp…
An X-ray investigation of Hickson 62
S. Sodani, E. De Filippis, M. Paolillo +2
We studied the X-ray properties of the Hickson Compact Group HCG62, in order to determine the properties and dynamic and evolutionary state of its hot gaseous halo. Our analysis re…
The Shapley super-cluster. New X-ray detections and mass distribution
E. De Filippis, S. Schindler, T. Erben
The largest and the deepest super-structure known today is the Shapley super-cluster. This is the sky area with the highest over-density of galaxy clusters and therefore also an id…
Abell 370: A Cluster with a Pronounced Triaxial Morphology
E. De Filippis, M. Sereno, M. W. Bautz
We here combine Sunyaev-Zel'dovich effect, X-ray observations and spectroscopic redshifts of member galaxies, to constrain the intrinsic three-dimensional shape of the galaxy clust…
XMM observation of the dynamically young galaxy cluster CL 0939+4713
E. De Filippis, S. Schindler, A. Castillo-Morales
We present an XMM observation of the distant galaxy cluster CL 0939+4713. The X-ray image shows pronounced substructure, with two main subclusters forming the cluster core. This is…
Recent CHANDRA and XMM observations of two very different galaxy clusters: RBS797 and CL 0939+4713
E. De Filippis, S. Schindler, A. Castillo-Morales
RBS797 and CL 0939+4713 are two intermediate red-shift clusters (). They have very different morphologies but both show surprisingly interesting structures. RBS797 loo…
Groups and clusters detection on DPOSS catalogs
E. Puddu, E. De Filippis, V. Strazzullo +5
We discuss the implementation and validation of a procedure aimed to detect groups and clusters of galaxies in DPOSS catalogs.
The Multiplicity Function of groups of galaxies from CRoNaRio catalogues
E. De Filippis, G. Longo, S. Andreon +4
The projected multiplicity function of galaxies gives (per square degree) the density of galaxy aggregates formed by N members. We use the CRoNaRio matched catalogues to derive the…
