A VLT spectroscopic survey of RX J0152.7-1357, a forming cluster of galaxies at z=0.837
R. Demarco, P. Rosati, C. Lidman +12
We present the results of an extensive spectroscopic survey of RX J0152.7-1357, one of the most massive distant clusters of galaxies known. Multi-object spectroscopy, carried out w…
Sub-mm detection of a high redshift Type 2 QSO
V. Mainieri, D. Rigopoulou, I. Lehmann +6
We report on the first SCUBA detection of a Type 2 QSO at z=3.660 in the Chandra Deep Field South. This source is X-ray absorbed, shows only narrow emission lines in the optical sp…
The spatial clustering of X-ray selected AGN and galaxies in the Chandra Deep Field South and North
R. Gilli, E. Daddi, G. Zamorani +10
We investigate the spatial clustering of X-ray selected sources in the two deepest X-ray fields to date, namely the 2Msec Chandra Deep Field North (CDFN) and the 1Msec Chandra Deep…
Photometric Redshift of X-Ray Sources in the Chandra Deep Field South
W. Zheng, V. J. Mikles, V. Mainieri +10
Based on the photometry of 10 near-UV, optical, and near-infrared bands of the Chandra Deep Field South, we estimate the photometric redshifts for 342 X-ray sources, which constitu…
Ks-band luminosity function of the z=1.237 cluster of galaxies RDCS J1252.9-2927
S. Toft, V. Mainieri, P. Rosati +4
We derive the Ks-band luminosity function (LF) of the z=1.237 massive X-ray luminous cluster of galaxies RDCS J1252.9-2927. Photometric redshifts, derived from deep multi-wavelengt…
Abundance Constraints and Direct Redshift Measurement of the Diffuse X-ray Emission from a Distant Cluster of Galaxies
Yasuhiro Hashimoto, Xavier Barcons, Hans Boehringer +4
We report on the XMM-Newton (XMM) observation of RXJ1053.7+5735, one of the most distant X-ray selected clusters of galaxies, which also shows an unusual double-lobed X-ray morphol…
