We propose to jointly observe with Chandra/ACIS and XMM/EPIC the unique largescale filamentary network of galaxies associated with the cluster ZwCl2341.1+0000 at z=0.3, discovered from the NVSS radio survey. Our optical/radiodata show that it is at least 10 Mpc in extent, and appears to be a superclusterin formation. It is the only known supercluster-scale filament structure whereboth (RASS) x-rays and evidence of intergalactic magnetic field have beendetected. Shocks from forming large structures can accelerate particles to thesevery high energies. We wish to detect thermal bremsstrahlung from this filamentas predicted from our simulations, which also predict micro-gauss magneticfields, and explore the role of shock-heating in the intergalactic medium.

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.
