COSMOS Observations: X-Ray

Imaging in the X-Ray domain allows the detection of Active Galaxy Nuclei and clusters of galaxies. Together with the ACS HST and spectroscopic data, the role of environment and galaxy morphology in the evolution of AGN activity will be measured.

We have so far secured 1.4 megaseconds of observing time with XMM/Newton in the AO3 and AO4 observing cycles. With the XMM data, 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.

Additional information on the XMM campaign can be found on the XMM-COSMOS website.
