cds-question@unistra.frsurveysx-ray-sourcesWe present the first set of XMM-Newton EPIC observations in the 2deg^2^ COSMOS field. The strength of the COSMOS project is the unprecedented combination of a large solid angle and sensitivity over the whole multi-wavelength spectrum. The XMM-Newton observations are very efficient in localizing and identifying active galactic nuclei (AGNs) and clusters, as well as groups of galaxies. One of the primary goals of the XMM-Newton Cosmos survey is to study the coevolution of active galactic nuclei as a function of their environment in the cosmic web. Here we present the log of observations, images, and a summary of first research highlights for the first pass of 25 XMM-Newton pointings across the field. In the existing data set we have detected 1416 new X-ray sources in the 0.52, 24.5, and 4.5-10keV bands to an equivalent 0.5-2keV flux limit of 7x10^-16^erg/cm^2^/s. The number of sources is expected to grow to almost 2000 in the final coverage of the survey. From an X-ray color-color analysis we identify a population of heavily obscured, partially leaky or reflecting absorbers, most of which are likely to be nearby, Compton-thick AGNs.2007ApJS..172...29Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/172/29CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/xmm : XMM-Newton Observation Log (XMM-Newton SOC, 2007)II/284 : COSMOS Multi-Wavelength Photometry Catalog (Capak+, 2007)J/ApJS/172/182 : Cluster of galaxies in XMM-COSMOS (Finoguenov+ 2007)J/ApJS/172/368 : XMM-Newton survey in COSMOS field.
