The Survey Science Centre of the XMM-Newton satellite released the first incremental version of the 2XMM catalogue in August 2008. Containing more than 220 000 X-ray sources, the 2XMMi was at that time the largest catalogue of X-ray sources ever published and thus constitutes an unprecedented resource for studying the high-energy properties of various classes of X-ray emitters such as AGN and stars. Thanks to the high throughput of the EPIC cameras on board XMM-Newton accurate positions, fluxes… Expand

Finding counterparts for All-sky X-ray surveys with Nway: a Bayesian algorithm for cross-matching multiple catalogues
We release the AllWISE counterparts and Gaia matches to 106,573 and 17,665 X-ray sources detected in the ROSAT 2RXS and XMMSL2 surveys with |b|>15. These are the brightest X-ray sources in the sky,Expand
3D mapping of the neutral X-ray absorption in the local interstellar medium: the Gaia and XMM-Newton synergy

A new sample of X-ray selected narrow emission-line galaxies. II. Looking for True Seyfert 2
A sample of X-ray and optically selected narrow emission-line galaxies (769 sources) from the 3XMM catalogue cross-correlated with SDSS (DR9) catalogue has been studied. Narrow-emission line activeExpand
The XMM-Newton survey in the H-ATLAS field
Wide area X-ray and far infrared surveys are a fundamental tool to investigate the link between AGN growth and star formation, especially in the low-redshift universe (z<1). The Herschel TerahertzExpand
A new sample of X-ray selected narrow emission-line galaxies - I. The nature of optically elusive AGN
Using the 3XMM catalogue of serendipitous X-ray sources, and the SDSS-DR9 spectroscopic catalogue, we have obtained a new sample of X-ray selected narrow emission line galaxies. The standard opticalExpand
X-Ray Sources in the 1.75 Ms Ultra Narrow Deep Field Observed by XMM-Newton
In this work, we present the results of the survey carried out on one of the deepest X-ray fields observed by the XMM-Newton satellite. The 1.75 Ms Ultra Narrow Deep Field (XMM175UNDF) survey is madeExpand
Using the Bright Ultrahard XMM-Newton survey to define an IR selection of luminous AGN based on WISE colours

Discovery of new members of the nearby young stellar association in Cepheus
Young field stars are hardly distinguishable from older ones because their space motion rapidly mixes them with the stellar population of the Galactic plane. Nevertheless, a careful target selectionExpand
