|Title||A Promising Ultra-High Velocity Outflow in PDS 456|
|Author||Dr Ehud Behar|
|Description||Although still controversial, ultra-high velocity outflows (UHVOs defined loosely by velocities exceeding 10,000 km-s) in AGNs are potentially the most exciting new discovery in AGN physics of the XMM-Newton and Chandra era. The luminous quasar PDS 456 is the brightest X-ray source among the grating-detected UHVOs. We propose to obtain the best yet high-resolution spectrum of a UHVO source. Using RGS for the soft X-ray band and EPIC for the Fe-K spectral region, we aim at measuring the UHVO velocity, column density, and thus its mass outflow rate and kinetic luminosity. Presently, the XMM-Newton-RGS with its high effective area is the only viable configuration that can guarantee the high S-N spectrum required for this study.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
