High-frequency water megamasers as precision probes of black holes, galaxies and cosmology: A case for a next-generation sub-mm/mm interferometer
Ingyin Zaw, C. M. Violette Impellizzeri, Dominic W. Pesce +8
Water megamasers in the circumnuclear disks of active galactic nuclei are among the most precise probes of supermassive black holes. VLBI imaging of 22 GHz disk masers has provided…
Parsec-scale SiO emission in the Galactic Center
N. Wenner, C. J. Chandler, J. M. Michail +2
The central 5 parsecs of our Galactic Center is rich in various molecular tracers. The region is observed to be hot, highly ionized, and volatile, resulting in complex chemistry an…
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-…
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…
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…
