Quasar outflows may play a crucial role in regulating the host galaxy,although the spatial scale of quasar outflows remain a major enigma, with theiracceleration mechanism poorly understood. The kinematic information of outflowis the key to understanding its origin and acceleration mechanism. Here, wereport the galactocentric distances of different outflow components for both asample and an individual quasar. We find that the outflow distance increaseswith velocity, with a typical value from several parsecs to more than onehundred parsecs, providing direct evidence for an acceleration happening at ascale of the order of 10 parsecs. These outflows carry ~1% of the total quasarenergy, while their kinematics are consistent with a dust driven model with alaunching radius comparable to the scale of a dusty torus, indicating that thecoupling between dust and quasar radiation may produce powerful feedback thatis crucial to galaxy evolution.

Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs
