| Abstract | We propose to perform a 130 ks observation of the Seyfert 1 galaxy H 0557-385,to obtain a high quality RGS spectrum of its very high column density ionisedoutflow (warm absorber). We will compare the properties of this outflow withthose of closer, less luminous Seyferts to investigate how the outflowcharacteristics depend on luminosity. Since Seyfert warm absorbers are just aghostly reminder of the much deeper, faster outflows in Broad Absorption Linequasars (BALQSOs), we will investigate whether this extreme object pointstowards the existence of an intermediate class of ionised outflow withproperties somewhere between those of nearby Seyferts and luminous BALQSOs. Thiswill provide an insight into how AGN outflows have evolved as the AGN population has dimmed with cosmic time. |

| 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. |
