Description We propose to observe a sample of 4 optically selected AGN pairs with projected separation ranging from 30 to 60 kpc with a total exposure time of 210 ks. The main objective of these observations are (a) to characterize the systems (luminosity and spectral shape) in the X-ray domain (b) to investigate their nuclear environment by measuring absorption and emission properties, only possible in the X-ray regime (c) to probe the nature of accretion flows in X-ray-detected AGN pairs, by comparing their properties with those observed in the optical and radio wavebands, and with theoretical models. This proposal is a pilot study for a broader project, designed to a first systematic study of the properties of an unbiased sample of multiple AGN, in an early stage of evolution, using multiband information.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
