An Outflow from the X-Ray Corona as the Origin of Millimeter Emission from Radio-quiet AGNs
The Astrophysical JournalRecent observations of radio-quiet active galactic nuclei have shown the presence of millimeter emission, whose origin remains unknown, from within parsec scales of the central black hole.
