However, this dichotomy, which aligns with the merger-driven growth of massive SMBHs, has been challenged by the discovery of a batch of jetted SMBHs with super-Eddington accretion rates. We here report a discovery of significant intra-day variability in the Balmer emission lines -and potentially in the FeII complex- in IRAS~16319+4725, a jetted super-Eddington AGN. This intra-day variability points to a new mechanism for the origin of the observed broad lines, in which the collisions between the jet and the surrounding material play a crucial role. We propose that the so-called jetted super-Eddington SMBHs have intrinsically low accretion activity, because the SMBH virial masses are significantly underestimated due to the inclusion of the broad-line emission resulting from such collisions.
