Abstract	The highest redshift quasars provide direct probes of the evolution ofsupermassive black holes (SMBHs) and the intergalactic medium at the earliestcosmic times. The discovery of a 7.8E8 Msun SMBH at z=7.54 (J1342+0928) put thestrongest constrains on the seed BH and BH accretion history (Banados et al.2018). Very recently, our team has found an even more extreme object, J1007 atz=7.5. J1007 is 1.8 times more luminous than J1342+0928 and hosts a SMBH withmass 1.6E^9 Msun, two times more massive than J1342+0928. The existence of J1007posts the most significant challenge to our understanding of the formation ofthe earliest SMBHs. Here, we propose deep XMM-Newton observations tocharacterize the accretion properties of J1007 and investigate its formation and growth mechanisms.

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.
