Title Studying Merger Driven Obscuration in Dual AGN


DOI https://doi.org/10.5270/esa-2vehdbz
Author Dr Michael Koss
Description During the process of merging, dual AGN, with two growing SMBHs hosted by a pair of merging galaxies, are predicted. Despite the much higher sensitivity of XMM above 5 keV than Chandra, only five dual AGN (<30 kpc) have been observed that can be resolved with XMM (>15. separation). We have selected a sample of 8 dual AGN to more than double this sample to study the increase of obscuration with merger stage. When combined with our recently accepted large Chandra and HST programs to study dual AGN at <10 kpc this study will form a well characterized complete study of all X-ray selected nearby dual AGN (z<0.07, <30 kpc) from the all sky ROSAT, XMM slew, or Swift BAT survey that is critical to understand AGN activation and obscuration in mergers.

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.
