The SKA-VLBI Perspective on Radio-Quiet AGN
Francesca Panessa, Tao An, James Petley +21
The accretion-ejection mechanism in Active Galactic Nuclei (AGN) remains a central open problem in astrophysics, tied to the role of AGN feedback in galaxy formation and evolution.…

Radio Emission from Broad Absorption Line Quasars
Sina Chen, Ehud Behar, Ari Laor +1
Broad Absorption Line Quasars (BALQs) generally exhibit significant outflows that may interact with the surrounding medium, resulting in radio emission. We selected a sample of 13…

A dichotomy in the 1-24 GHz parsec-scale radio spectra of radio-quiet quasars
Sina Chen, Ari Laor, Ehud Behar +3
We present the pc-scale radio spectra of a representative sample of 13 Palomar-Green radio-quiet quasars, based on our new Very Long Baseline Array (VLBA) observations at 8.4 and 2…
