e-EVN: EN005G, EC075, EG102K
QSO J0903+5012 with redshift of 6.31 is the most distant radio quasar up to date. Its radio flux at L band is up to 0.9 Jy, making it one of the most luminous quasars. Imaging this special QSO may help understand the radio structure of AGN in the early universe. Multi-frequency observations are needed to study its magnetic field and obtain the spectral index, which may give some explanation of its radio structure.
