Simultaneous observations of hard state LMXBs with XMM-Newton and the ISAACinfrared camera on the VLT can reveal the direct connection between accretiondisc variability and variations from the jet. A recent triggered observation ofGX 339-4 revealed the first such correlation and showed, surprisingly, that thedisc is better correlated with the jet IR emission than the power-law is,suggesting that the disc plays a key role in powering the jet. Here we requestan XMM-Newton open time observation (30 ksec exposure) simultaneous withVLT-ISAAC (3 hours) observations of the .persistent. LMXB SWIFTvirgulJ1753.5-0127(with a supporting optical observation to be proposed for separately), todetermine whether this exciting result can be applied more generally.

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.
