| Abstract | In recent years, the study of the correlated X-ray/OIR fast variability inblack-hole transients (BHTs) is showing more and more promising results. GRS1915+105 was one of the first BHTs to be studied with a multiwavelengthapproach, showing the first strong evidences for a disk-jet connection. As oftoday, only few X-ray-OIR simultaneous observations have been reported of thissource. Here, we propose to observe GRS1915+105 simultaneously with XMM andHAWK-I@VLT, using high time resolution modes at both wavelengths. We ask toperform 5 (7 ks apiece) XMM observations, matched by 5 (1 hour apiece)HAWKiI@VLT observations. These data will allow us to study the disc-jetconnection in different accretion regimes, and have an overall picture of the complex evolution of this extreme source. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
