The Millimeter/X-ray Relation in Rapidly Accreting Supermassive Black Holes at

Sophie M. Venselaar, Claudio Ricci, Santiago Del Palacio +12

A tight correlation between nuclear millimeter and X-ray emission has recently been found in nearby () and low-Eddington ratio () radio-quiet Active G…

BASS. LI. Cool gas supply of HI-massive local Seyfert galaxies

Jeein Kim, Aeree Chung, O. Ivy Wong +19

We present neutral atomic hydrogen (HI) imaging observations of 22 HI-rich (), hard X-ray-selected local Seyferts to explore how cool gas is su…

Molecular Gas in Major Mergers Hosting Dual and Single AGN at <10 kpc Nuclear Separations

Makoto A. Johnstone, Ezequiel Treister, Franz E. Bauer +24

We present high-resolution (50100 pc) Atacama Large Millimeter Array (ALMA) observations of CO(2-1) or CO(1-0) emission in seven local ( 0.05)…

BASS LIII: The Eddington Ratio as the Primary Regulator of the Fraction of X-ray Emission in Active Galactic Nuclei

Kriti Kamal Gupta, Claudio Ricci, Alessia Tortosa +20

Active galactic nuclei (AGN) emit radiation via accretion across the entire energy spectrum. While the standard disk and corona model can somewhat describe this emission, it fails…

BASS. XLIX. Characterization of highly luminous and obscured AGNs: local X-ray and [NeV]3426 emission in comparison with the high-redshift Universe

Alessandro Peca, Michael J. Koss, Kyuseok Oh +21

We present a detailed analysis of the most luminous and obscured Active Galactic Nuclei (AGNs) detected in the ultra-hard X-ray band (14-195 keV) by Swift/BAT. Our sample comprises…

ALMA observation of evolving magnetized corona in the radio-quiet changing-state AGN NGC 1566

Arghajit Jana, Claudio Ricci, Sophie M. Venselaar +9

The origin of compact millimeter (mm) continuum emission from radio-quiet AGNs (RQAGNs) is still not fully understood. Changing-state AGNs (CSAGNs) display rapid and strong variabi…
