Are fossil groups a challenge of the Cold Dark Matter paradigm?
Stefano Zibetti, Daniele Pierini, Gabriel W. Pratt
We study six groups and clusters of galaxies suggested in the literature to be `fossil' systems (i.e. to have luminous diffuse X-ray emission and a magnitude gap of at least 2 mag-…
Diffuse stellar emission in X-ray luminous galaxy clusters at z~0.3 I. Is the diffuse optical light boosted and rejuvenated in merging clusters?
D. Pierini, S. Zibetti, F. Braglia +4
[Abridged] We searched for diffuse stellar emission around BCGs in three of the most X-ray luminous clusters found at z~0.3 in the REFLEX cluster survey and observed with XMM-Newto…
Constraining MgII absorbers with the SDSS
Brice Ménard, Stefano Zibetti, Daniel Nestor +1
Using a large sample of MgII absorbers with 0.4<z<2.2 detected by Nestor et al (2005) in the Early Data Release of the SDSS, we present new constraints on the physical properties o…
Constraining the photometric properties of MgII absorbing galaxies with the SDSS
Stefano Zibetti, Brice Menard, Daniel Nestor +1
Using a sample of nearly 700 quasars with strong (W_0(2796)>0.8 Angstrom) MgII absorption lines detected in the Early Data Release of the SDSS, we demonstrate the feasibility of me…
The Fourth Data Release of the Sloan Digital Sky Survey
J. K. Adelman-McCarthy et al.
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
NIR observations of dEs in the Virgo cluster: a structural continuity with giant Ellipticals
Stefano Zibetti, the GOLDMiNe Research Team
The structural properties of a sample of 50 dEs in the Virgo cluster are here derived from Near InfraRed (NIR, H-band 1.65 micron) surface photometry and analysed. One-dimensional…
