The radio emission in radio-quiet quasars: the VLBA perspective
Sina Chen, Ari Laor, Ehud Behar +2
The origin of the radio emission in radio-quiet quasars (RQQ) is not established yet. We present new VLBA observations at 1.6 and 4.9 GHz of ten RQQ (nine detected), which together…

Mildly Relativistic Motion in the Radio Quiet Quasar PG 1351+640
Ailing Wang, Tao An, Shaoguang Guo +8
Measuring the proper motion of the emission component in radio-quiet quasars (RQQs) could help to distinguish between the origins of the radio emission and to understand whether th…
