|Title||Fast multi-wavelength variability from a BH: speed, size and geometry of a jet|
|Author||Dr Piergiorgio Casella|
|Description||Correlated fast multi-wavelength variability is quickly becoming a key tool for studying the physics of accretion-ejection of relativistic jets. Using X-ray-IR simultaneous data we have recently discovered vibrations from a relativistic jet down to 62.5 ms time scale, which allowed us to estimate the jet speed and size. Our results from further data also show that the jet properties depend on the spectral state of the BH. Here, we propose to monitor the outburst evolution of a BH transient with XMM, simultaneously with ground-based OIR facilities, in order to apply the same technique to different states. We will monitor the energetic and geometrical changes in the jet, and its relation with the accretion disk. We propose to perform up to 12 short XMM observations.|

|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.
