|Title||WISE Discovery of the Largest Sample of Obscured Dual AGNs: An XMM-Newton Follow|
|Author||Dr Shobita Satyapal|
|Description||Despite decades of searching, observationally confirmed cases of binary AGNs are extremely rare, and most have been discovered serendipitously. Using the all-sky WISE survey, we identified a population of almost 200 optically quiescent strongly interacting galaxies that display MIR signatures of powerful AGNs.Expanding on our Chandra program, which confirmed duals in 4 out of 6 observed targets, we propose to observe with XMM the 3 brightest dual AGNs. The superior sensitivity of XMM is crucial to model in detail the X-ray spectrum necessary to determine the intrinsic absorption, estimate the bolometric luminosity of the nuclear region, and constrain the black hole mass. This program is complementary to optical searches and will be the first detailed investigation into this population.|

|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.
