We propose to examine the X-ray spectral and simultaneous Optical Monitorcharacteristics of a sample of very strong UV-Fe II emitters selected from theSloan Digital Sky Survey (SDSS). Strong optical Fe II emitters are known to theX-ray community as narrow-line Seyfert 1 galaxies (NLS1) and they exhibit veryextreme X-ray properties. Our sample of strong UV-Fe II has not beensignificantly detected in the RASS leading to the possibility that their X-rayspectra are not typical of NLS1. We propose to observe 8 objects for 10 ks eachfor a total requested time of 80 ks.

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.
