Abstract:
We propose the observation of two new radio-bright z>6 jetted QSOs. The primary aim of the observation is to characterise their X-ray emission for the first time. Thanks to their very high redshift, these sources are the ideal candidates to study the evolution of jetted QSOs by providing constraints on the role played by relativistic jets in the still poorly explored primordial Universe. The angular resolution of Chandra and the requested time of 60 and 90ksec for the two targets will allow us to: (1) firmly determine the X-ray flux and spectral features of the core; (2) detect the possible presence of an extended X-ray emission produced by their jets. These points will be instrumental to test the IC/CMB mechanism for X-ray jets in QSOs at the end of the re-ionisation epoch.
