IC 485:a new candidate disk-maser galaxy at 100 Mpc distance. Milliarcsecond resolution study of the galaxy nucleus and of the megamaser
E. Ladu, A. Tarchi, P. Castangia +4
Masers are a unique tool to investigate the emitting gas in the innermost regions of AGNs and to map accretion disks and tori orbiting around supermassive black holes. IC485, which…
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…
Enhancing the H2O Megamaser Detection Rate Using Optical and Mid-infrared Photometry
C. Y. Kuo, A. Constantin, J. A. Braatz +8
Water megamasers from circumnuclear disks in galaxy centers provide the most accurate measurements of supermassive black hole masses and uniquely probe the sub-parsec accretion pro…
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…
