Imaging the high-z quasar W2246
W2246-0526 at redshift z~4.6 has been known as the most luminous galaxy in the universe. Recent multiwavelength follow-up observations suggest that it is experiencing the key transition stage during the evolution of the most massive galaxies and being on its road to become an unobscured quasar, when AGN feedback is already in full action. Thus W2246-0526 is a peculiar candidate for studying the early assembly of the most massive galaxy and the interplay between host galaxy and its central SMBH. We propose EVN observations of the radio counterpart of W2246-0526 at 1.6 GHz for totally 7 hours to image non-thermal radio emission. High-resolution radio observation using VLBI will offer a sharp and unobscured view of the compact AGN-related structures. The milli-arcsecond radio imaging will also allow us to provide the most direct evidence for AGN jet activity in the most luminous galaxy.
