Event Horizon Telescope observations of the jet launching and collimation in Centaurus A

Michael Janssen, Heino Falcke, Matthias Kadler +236

Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…

Polarimetric properties of Event Horizon Telescope targets from ALMA

Ciriaco Goddi, Ivan Marti-Vidal, Hugo Messias +31

We present the results from a full polarization study carried out with ALMA during the first VLBI campaign, which was conducted in Apr 2017 in the 3mm and 1.3mm bands, in con…

A restless supermassive black hole in the galaxy J0437+2456

Dominic W. Pesce, Anil C. Seth, Jenny E. Greene +4

We present the results from an observing campaign to confirm the peculiar motion of the supermassive black hole (SMBH) in J0437+2456 first reported in Pesce et al. (2018). Deep obs…

A More Efficient Search for H2O Megamaser Galaxies : The Power of the X-ray and Mid-infrared Photometry

C. Y. Kuo, J. Y. Hsiang, H. H. Chung +10

We present a new investigation of the dependence of H2O maser detection rates and properties on the mid-IR AGN luminosity, L_AGN, and the obscuring column density, N_H, based on mi…

The Megamaser Cosmology Project. XII. VLBI Imaging of HO Maser Emission in Three Active Galaxies and the Effect of AGN Winds on Disk Dynamics

C. Y. Kuo, J. A. Braatz, C. M. V. Impellizzeri +7

We present VLBI images and kinematics of water maser emission in three active galaxies: NGC 5728, Mrk 1, and IRAS 08452-0011. IRAS 08452-0011 is a triple-peaked H2O megamaser, cons…
