Torus feeding and outflow launching in the active nucleus of the Circinus galaxy

Wout M. Goesaert, Konrad R. W. Tristram, C. M. Violette Impellizzeri +4

Context: Most active galactic nuclei (AGN) are believed to be surrounded by a dusty molecular torus on the parsec scale which is often embedded within a larger circumnuclear disk (…

First polarization study of the M87 jet and active galactic nuclei at submillimeter wavelengths with ALMA

Ciriaco Goddi, Douglas F. Carlos

We present full-polarization observations at mm (345 GHz) conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) toward Messier 87 (M87) and seven other…

Demographics of black holes at 100 R scales: accretion flows, jets, and shadows

Dhanya G. Nair, Neil M. Nagar, Venkatessh Ramakrishnan +87

Using the Event Horizon Telescope (EHT), the gravitationally lensed rings around the supermassive black holes (SMBHs) in Messier 87 (M87) and Sagittarius A* (Sgr A*) have now been…

The Detection of HO Maser Emission from mid-IR Red Galaxies

C. Y. Kuo, C. Y. Tai, A. Constantin +7

We report the detection of HO maser emission in 4 out of 77 (5.2%) mid-IR red galaxies that meet the color criteria of and and are classified as Type-…

The Discovery of Polarized Water Vapor Megamaser Emission in a Molecular Accretion Disk

Jack F. Gallimore, C. M. Violette Impellizzeri, Samaneh Aghelpasand +3

For the first time in an extragalactic source, we detect linearly polarized water maser emission associated with the molecular accretion disk of NGC 1068. The position angles of th…

What Determines the Boundaries of H2O Maser Emission in an X-ray Illuminated Gas Disk ?

C. Y. Kuo, F. Gao, J. A. Braatz +7

High precision mapping of H2O megamaser emission from active galaxies has revealed more than a dozen Keplerian H2O maser disks, which enable a ~4% uncertainty estimate of the Hubbl…
