The Chandra Deep Field South: Optical Spectroscopy I
G. P. Szokoly, J. Bergeron, G. Hasinger +15
We present the results of our spectroscopic follow-up program of the X-ray sources detected in the 942 ks exposure of the Chandra Deep Field South (CDFS). 288 possible counterparts…
Deep near-infrared imaging of RDCS J1252.9-2927 at z=1.237: The colour-magnitude diagram
C. Lidman, P. Rosati, R. Demarco +4
We present deep SofI and ISAAC near-infrared imaging data of the X-ray luminous galaxy cluster RDCS J1252.9-2927. The ISAAC data were taken at the ESO Very Large Telescope under ve…
Chandra and XMM-Newton Observations of RDCS1252.9-2927, A Massive Cluster at z=1.24
P. Rosati, P. Tozzi, S. Ettori +10
We present deep Chandra and XMM obervations of the galaxy cluster RDCS1252.9-2927, which was selected from the ROSAT Deep Cluster Survey (RDCS) and confirmed by extensive spectrosc…
A Possible New Population of Sources with Extreme X-Ray / Optical Ratios
Anton M. Koekemoer, D. M. Alexander, F. E. Bauer +13
We describe a possible new class of X-ray sources that have robust detections in ultra-deep Chandra data, yet have no detections at all in our deep multi-band GOODS Hubble Space Te…
Tracing the large scale structure in the Chandra Deep Field South
R. Gilli, A. Cimatti, E. Daddi +16
We report the discovery of large scale structures of X-ray sources in the 1Msec observation of the Chandra Deep Field South. Two main structures appear as narrow (Delta_z < 0.02) s…
