|Title||How Powerful Are Quasar Outflows?|
|Author||Prof William Brandt|
|Description||X-ray absorption studies of quasar outflows with low-resolution CCD spectroscopy cannot reliably determine the outflow kinetic luminosity. We therefore propose an ambitious long-look observation to obtain the first high-quality grating spectroscopy of a mini-BAL quasar (PG 1114+445). Grating spectroscopy of a small sample of local Seyfert galaxies has led to highly regarded accurate determinations of their wind properties. The proposed extension of grating spectroscopy to the first mini-BAL quasar level AGN will determine if the outflow becomes as powerful as required in current AGN feedback scenarios. The 375,000 count EPIC spectra from this long-look will enable unprecedented complementary studies of high-energy absorption features and iron K emission.|

|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.
