| Description | 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 ionised outflow (warm absorber). We will compare the properties of this outflow with those of closer, less luminous Seyferts to investigate how the outflow characteristics depend on luminosity. Since Seyfert warm absorbers are just a ghostly reminder of the much deeper, faster outflows in Broad Absorption Line quasars (BALQSOs), we will investigate whether this extreme object points towards the existence of an intermediate class of ionised outflow with properties somewhere between those of nearby Seyferts and luminous BALQSOs. This will provide an insight into how AGN outflows have evolved as the AGN population has dimmed with cosmic time. |

| 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. |
