| Description | The warm absorber of the low-luminosity Seyfert NGC 3227 is characterized by low levels of ionization, making it relatively unique among Seyferts. A high-quality grating spectrum, taken when the source is not in an obscured state, is needed for further detailed study of the warm absorber. We propose a 110 ksec XMM-Newton observation to obtain RGS and EPIC spectra, probe the warm and neutral absorber properties, search for expected signatures of dust embedded in the warm absorber, and search for flux-dependent spectral changes. We will also characterize energy-dependent timing properties to fully explore Seyfert/X-ray Binary analogies, and search for correlated X-ray/UV flux variability to test reprocessing models. |

| 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. |
