We have detected a highly blueshifted (7.6 keV at the source frame) emissionfeature in the ASCA spectra of the unusual Narrow-line Seyfert 1 galaxy RXJ0136.9-3510. At ASCA resolution it is impossible to tell if the feature is asingle line or a combination of lines nor if the feature is due to He-like orH-like Fe. The line profile can tell us where the bulk of the emission origin-ates: A low velocity dispersion would favor a wind/outflow origin, while a hi-gher dispersion may allow for an ionized disk reflection origin. Strong absor-ption and resonant scattering could also produce blueshifted line. To acquirebetter resolution spectrum to constrain the origin of the line via detailedphysical modeling, we propose 50 ks XMM-Newton observations of RXJ0136.9-3510.

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.
