Description | We propose EPIC observations of the microquasar SS 433, the only known persistent superaccretor in the Galaxy. Previous studies of the XMM data showed that different parts of SS 433 spectrum are dominated by different sources of radiation. Preliminary results of the cross-correlation analysis of low- resolution RXTE spectra and existing short-duration XMM data, revealed correlations in variability between different energy ranges with time lags of 20 s. We request a longer (115 ks) observations in the timing mode to obtain high- resolution data, sufficient for the cross-correlation and variability analysis. These new data will give us the unique opportunity to investigate directly the non-stationary processes and spatial structure of the most inner parts of the supercritical accretion disk. |

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. |
