Abstract | We propose X-ray spectroscopy of type 2 QSO candidates chosen based on veryluminous optical emission lines and Seyfert 2 type classification in the IRAS 1Jy sample of ultraluminous infrared galaxies (ULIRGs). Our goals are (1) tomeasure intrinsic luminosity to test whether the main power source inSeyfert-type ULIRGs is an AGN if the AGN is Compton thin, (2) to constrain thegeometry of obscuring matter from Fe-K lines and to compare them with lessluminous AGNs. These data will be a basis to take a census of type 2 QSOs inon-going/future IR/X-ray survey and to perform hard X-ray follow up to fullyunderstand the long-sought class of AGNs. |

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. |
