High redshift quasars probe the formation and evolution of supermassive blackholes (SMBHs) at early cosmic time. Here we propose XMM-Newton observations ofJ0439 at z = 6.5, the most distant lensed quasar known to date. Aided by amagnification factor of virgul50, it is the brightest quasar in optical and FIR atz>6 and unique target for the study of SMBH accretion at the reionization era,with typical BH mass but extremely high anticipated X-ray flux. With only 90 ksnet exposure, a high quality X-ray spectrum with total counts of virgul8000 countscan be obtained, providing a high S/N X-ray view of an early SMBH for the firsttime. We will search for the ultra-fast outflows and measure the X-rayluminosity, spectral slope, coronal properties and optical-to-X-ray SED of this quasar.

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.
