| Abstract | Dual AGN are predicted to be a critical stage of galaxy merger-driven SMBHgrowth. Most dual AGN searches target late-stage mergers, while few studies haveprobed dual AGN at larger separations. Yet, simulations predict that AGN canbecome Compton-thick after the first pericenter passage of the hosts, suggestingthat wider separation dual AGN may represent an important stage of growth alongthe merger sequence. We propose a 170ks X-ray (EPIC) and UV (OM) XMM-Newtonprogram to observe 23 wide-separation dual AGN candidates selected using opticalspectra and mid-IR imaging. Using XMM, we will (1) search for dual X-ray pointsources, (2) constrain the X-ray spectral properties of each source, and (3)perform SED fitting using archival photometry in concert with XMM EPIC and OM imaging. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
