The origins of radio emission from radio-quiet Quasi-Stellar Objects (QSOs)
Abstract
One of the most puzzling aspects of active galactic nuclei is the dominant physical origin of their radio emission. For radio-loud objects, it's clear that the dominant origin is the AGN radio-jet. But for radio-quiet objects, there is an ongoing controversy in the literature. Potential sources of radio emission include black hole spin, (scaled-down) AGN jets, shocks from AGN driven winds, and host galaxy star formation. In reality, all of these may contribute, but the question remains as to which one (if any) is the dominant source over different sources among the radio-quiet QSO population. I will present new results that are part of an ongoing study to constrain the AGN-jet emission from radio-quiet QSOs using high-resolution VLBI observations.
