BASS XXXIV: A Catalog of the Nuclear Mm-wave Continuum Emission Properties of AGNs Constrained on Scales 100--200 pc

Taiki Kawamuro, Claudio Ricci, Richard F. Mushotzky +25

We present a catalog of the millimeter-wave (mm-wave) continuum properties of 98 nearby ( 0.05) active galactic nuclei (AGNs) selected from the 70-month Swift/BAT hard X-ray c…

Supermassive black hole feeding and feedback observed on sub-parsec scales

Takuma Izumi, Keiichi Wada, Masatoshi Imanishi +8

Active galaxies contain a supermassive black hole at their center, which grows by accreting matter from the surrounding galaxy. The accretion process in the central ~10 parsecs has…
