One of the biggest mysteries in modern astrophysics is the mechanism driving thelaunching of jets from compact objects. Observing how jets which accompanysuper-Eddington accretion couple to the inflow, will test the physics of thelaunching and yield a major step forwards in our understanding. We have recentlyshown that the radio core of the ULX, Ho II X-1 varies on timescales ofmins-days, allowing us to probe this coupling for the first time. XMM-Newton andVLA together are the only instruments capable of delivering this ground-breakingscience and for which we are proposing a series of 10 simultaneous observations.To place the physics of the coupling into context, we are also requesting aseries of Swift snapshots which we will match with AMI observations at 16 GHz.

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.
