The XMM-Newton wide-field survey in the COSMOS field: VI. Statistical properties of clusters of galaxies
A. Finoguenov, L. Guzzo, G. Hasinger +30
We present the results of a search for galaxy clusters in the first 36 XMM-Newton pointings on the COSMOS field. We reach a depth for a total cluster flux in the 0.5-2 keV band of…
The XMM-Newton wide-field survey in the COSMOS field: III. optical identification and multiwavelength properties of a large sample of X-ray selected sources
M. Brusa, G. Zamorani, A. Comastri +31
[ABRIGED] We present the optical identification of a sample of 695 X-ray sources detected in the first 1.3 deg^2 of the XMM-COSMOS survey, down to a 0.5-2 keV (2-10 keV) limiting f…
Large Structures and Galaxy Evolution in COSMOS at z < 1.1
N. Scoville, H. Aussel, A. Benson +25
We present the first identification of large-scale structures (LSS) at z in the Cosmic Evolution Survey (COSMOS). The structures are identified from adaptive smoothing of g…
The X-ray Properties of Early-Type Galaxies in the Extended Chandra Deep Field-South
B. D. Lehmer, W. N. Brandt, D. M. Alexander +8
We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Fiel…
A wide angle tail radio galaxy in the COSMOS field: evidence for cluster formation
V. Smolcic, E. Schinnerer, A. Finoguenov +19
We have identified a complex galaxy cluster system in the COSMOS field via a wide angle tail (WAT) radio galaxy consistent with the idea that WAT galaxies can be used as tracers of…
Mid-infrared Spitzer spectra of X-ray selected Type 2 QSOs: QSO2s are not ULIRGs
E. Sturm, G. Hasinger, I. Lehmann +5
We have performed a spectroscopic study of 7 Type 2 QSOs using the mid-infrared spectrometer IRS on board the Spitzer Space Telescope. These are (to our knowledge) the first mid-IR…
