Gauging the dark matter fraction in a S0 galaxy at z=0.47 through gravitational lensing from deep HST/ACS imaging
G. Covone, M. Paolillo, N. R. Napolitano +9
We analyze a new gravitational lens, OAC-GL J1223-1239, serendipitously found in a deep I-band image of the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). The lens…
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…
Further spectroscopic observations of the CSL-1 object
M. Sazhin, M. Capaccioli, G. Longo +2
CSL-1 is a peculiar object (R.A._{2000}= 12h 23m 30.5"; Dec_{2000}= -12deg 38' 57.0") which, for its photometric and spectroscopic properties, is possibly the first case of gravita…
Photometric validation of a model independent procedure to extract galaxy clusters
E. Puddu, S. Andreon, G. Longo +3
By means of CCD photometry in three bands (Gunn g, r, i) we investigate the existence of 12 candidate clusters extracted via a model independent peak finding algorithm (\cite{memsa…
Deep ROSAT-HRI observations of the NGC 1399/NGC 1404 region: morphology and structure of the X-ray halo
M. Paolillo, G. Fabbiano, G. Peres +1
We present the analysis of a deep (167 ks) ROSAT HRI observation of the cD galaxy NGC 1399 in the Fornax cluster. Using both HRI and, at larger radii, archival PSPC data, we find t…
Luminosity function of clusters of galaxies
M. Paolillo, S. Andreon, G. Longo +5
The composite galaxy luminosity function (hereafter LF) of 39 Abell clusters of galaxies is derived by computing the statistical excess of galaxy counts in the cluster direction wi…
