| Abstract | Relativistic jets are thought to play a key role on the formation of massivegalaxies and supermassive black holes. Radio and X-ray observations provide themost direct probes of SMBHs accretion mechanisms and jets physics. However,currently there is a dearth of radio sources at z>=7, which in turn are a keymissing population for future 21 cm absorption studies well within the epoch ofreionization. We propose quasi-contemporary VLA/XMM observations of a newredshift-record radio source at z=7, for which archival non-simultaneous 1.4 and3.0GHz data reveal an atypical sharply rising spectrum of index +0.6 that couldbe compatible with a blazar. |

| 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. |
