The XMM-Newton wide-field survey in the COSMOS field. IV: X-ray spectral properties of Active Galactic Nuclei
V. Mainieri, G. Hasinger, N. Cappelluti +25
We present a detailed spectral analysis of point-like X-ray sources in the XMM-COSMOS field. Our sample of 135 sources only includes those that have more than 100 net counts in the…
COSMOS : Hubble Space Telescope Observations
N. Scoville, A. Benson, A. W. Blain +50
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Her…
The evolution of the number density of large disk galaxies in COSMOS
M. T. Sargent, C. M. Carollo, S. J. Lilly +17
We study a sample of approximately 16,500 galaxies with I_AB <= 22.5 in the COSMOS field. Structural information on the galaxies is derived by fitting single Sersic models to their…
NICMOS Status
Roelof S. de Jong, Santiago Arribas, Elizabeth Barker +15
We provide an overview of the most important calibration aspects of the NICMOS instrument on board of HST. We describe the performance of the instrument after the installation of t…
