Abstract | Ultraluminous infrared Galaxies (ULIRGs) are interacting galaxies with infraredluminosity comparable to quasars.An evolutionary relation with quasars arestrongly suggested, but the origin of their infrared emission (SB or AGN) isstill a major issue under debate. Our recent study of ULIRGs observed with ASCAsuggests that the AGN in ULIRGs generally indicates the features of narrow-lineSeyfert 1 galaxies(NLSy1s). This might be the evidence that the AGN in ULIRGshas a light blackhole and high mass accretion rate, and hence is now underevolution to a quasar.To examine the properties of the AGN in ULIRGs directlyand reveal the connection with quasars, we propose systematic observations oftype 1 ULIRGSs with XMM-Newton. |

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. |
