Description GRS 1915+105 is the most prominent microquasar and the most energetic object in our Galaxy. It has remained unique among its class for the large variety of temporal behaviours in different time scales. Multiwavelength observations showing radio, IR and X-ray oscilations, with time delays depending on the wavelength, revealed in the past the intimate link between the accretion disc and the jet ejection. However, the mechanism of jet formation and the origin of the delay between the flares in different wavelengths remains unclear. Here we propose simultaneous X-ray and IR observations of GRS 1915+105 with unprecedented high time resolution, using EPIC-pn in Burst mode and VLT-ISAAC.s Aladdin array in its new Burst mode, with integration times as short as 3.2ms.

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.
