XMM-Newton COSMOS |
 |
(P.I. Günther Hasinger) |
| The
main and unique feature
of the XMM-Newton
follow-up of the COSMOS
field is to combine the XMM-Newton
X-ray throughput, the highly efficient multiplexing of VLT/Vimos
and
the unprecedented solid angle coverage of difraction limited HST
imaging over the largest solid angle and sensitivity ever achieved. We
shall probe for the first time the 3D clustering as a function of
redshift in the X-ray band and detect sufficient numbers of AGN to
probe the accretion history at high redshift for the first time. NEWS: 2009 January 15th: The XMM-COSMOS catalog has been released to the public via the IRSA archive. An accompanying paper describing the catalog has been accepted by the Astronomy and Astrophysics Journal (Cappelluti et al. 2009). A list of papers based on XMM-COSMOS data publsihed in the past years or accepted for publication is available at this link |

New images from the XMM-COSMOS field have been produced by Alexis
Finoguenov and Nico Cappelluti. The latest XMM
image of the COSMOS field can always be found here.
Nico Cappelluti has also produced the exposure map for all the
available pointings as well as the distribution of exposure times
for PN and MOS (last column).

Abstract
We propose a mosaic of
medium-deep XMM pointings to homogeneously cover a large (2
sq. degrees) and contiguous area of the COSMOS/VIMOS field.
This field is (1) part of a breakthrough spectroscopic
survey to be carried out by the z-COSMOS team, using 60
(already awarded) VLT nights with the VIMOS
spectrograph, to provide ~50000 galaxy redshifts between 0.3 and 2.5
and, (2) target of the
Cosmos HST/ACS treasury
program, carried out using 640 HST
orbits, to understand the interplay between Large Scale
Structure, evolution and the formation of galaxies, Dark
Matter - Energy and AGN. The main scientific objectives are the study
of the formation and evolution of supermassive black holes, the cosmic
evolution of their spatial distribution and the correlation with galaxy
morphology and evolution.
