We propose a 130 ks observation of the MUSE Ultra Deep Field (MUDF) which, uponcompletion, will be the deepest (up to 300h) spectroscopic survey ever done withMUSE/VLT. MUDF is centered on a unique field (P2139-443) of two bright,physically associated quasars at zvirgul3.23, separated by virgul500 kpc in projection.Both quasars are embedded within large Ly nebulae (virgul100 kpc), which aresuggestive of an extended filament connecting the two halos of the quasars. Ourmain aim is to collect high-quality X-ray spectra to characterise the physicalproperties (e.g. X-ray slope, luminosities, gas column densities, accretionrate) in the innermost region of this pair with physically associated extendedLy nebulae.

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.
