Description | We propose a triggered ToO observation of the Narrow-Line Seyfert 1 galaxy Mkn 335 in its low X-ray flux state for 200 ks with XMM-Newton. Mkn 335 is a very bright NLS1 with an exceptional broad iron line. In 2007 we caught it in an extreme low X-ray flux state. Still bright enough in its low-state, it offeres a unique opportunity to distinguish between two AGN key spectral models, the partial covering absorber versus reflection models, and to study the .warm. circumnuclear BLR gas with the RGS in detail. These studies can only be done in an extreme low-state. |

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. |
