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…

Accretion disk versus jet orientation in HO megamaser galaxies

F. Kamali, C. Henkel, S. Koyama +10

An essential part of the paradigm describing active galactic nuclei is the alignment between the radio jet and the associated rotation axis of the sub-pc sized accretion disks. Bec…

The Multifrequency Behavior of Sagittarius A*

A. Eckart, M. Zajacek, M. Parsa +15

The Galactic Center is the closest galactic nucleus that allows us to determine the multi-frequency behavior of the supermassive black hole counterpart Sagittarius A* in great deta…

Molecular line emission in NGC 4945, imaged with ALMA

C. Henkel, S. Muehle, G. Bendo +31

NGC 4945 is one of the nearest (~3.8 Mpc; 1" ~ 19 pc) starburst galaxies. ALMA band 3 (3--4\,mm) observations of HCN, HCO+, CS, C3H2, SiO, HCO, and CH3C2H were carried out with ~2"…

Extragalactic maser surveys

C. Henkel, J. -E. Greene, F. Kamali

Since the IAU (maser-)Symposium 287 in Stellenbosch/South Africa (Jan. 2012), great progress has been achieved in studying extragalactic maser sources. Sensitivity has reached a le…

Radio continuum of galaxies with HO megamaser disks: 33 GHz VLA data

F. Kamali, C. Henkel, A. Brunthaler +10

We investigate the nuclear environment of galaxies with observed 22 GHz water megamaser in their subparsec edge-on accretion disks, using 33 GHz (9mm) radio continuum data from VLA…
