| Abstract | As the final element of QUEST, a comprehensive multiwavelength program on localmassive gas-rich mergers (ULIRGs & QSOs), we propose to obtain EPIC imaging dataon the remaining 10 of 25 PG QSOs in the QUEST sample that have not beenobserved by XMM or Chandra. The main goal of the program is to determine theevolution of the energy source and the feeding/growth rate of BHs along themerger sequence (from mergers to ULIRGs to QSOs) as well as to find if there isa fundamental link between ULIRGs, IR-excess QSOs, and optical QSOs. Theseobservations will supplement data already obtained with HST, SST, VLT, and IRAM.The X-ray data will become part of graduate student S. Tengs Ph.D. thesis. |

| 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. |
