Evidence for a receding dust sublimation region around a supermassive black hole
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +6
The near-IR emission in Type 1 AGNs is thought to be dominated by the thermal radiation from dust grains that are heated by the central engine in the UV/optical and are almost at t…
Probing the innermost dusty structure in AGN with mid-IR and near-IR interferometers
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +5
With mid-IR and near-IR long-baseline interferometers, we are now mapping the radial distribution of the dusty accreting material in AGNs at sub-pc scales. We currently focus on Ty…
The innermost dusty structure in active galactic nuclei as probed by the Keck interferometer
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +5
We are now exploring the inner region of Type 1 active galactic nuclei (AGNs) with the Keck interferometer in the near-infrared. Adding to the four targets previously studied, we r…
Exploring the inner region of Type 1 AGNs with the Keck interferometer
Makoto Kishimoto, Sebastian F. Hoenig, Robert Antonucci +4
The exploration of extragalactic objects with long-baseline interferometers in the near-infrared has been very limited. Here we report successful observations with the Keck interfe…
A Search for H2O Megamasers in High-z Type-2 AGNs
Nicola Bennert, Richard Barvainis, Christian Henkel +1
We report a search for H2O megamasers in 274 SDSS type-2 AGNs (0.3 < z < 0.83), half of which can be classified as type-2 QSOs from their [OIII] 5007 luminosity, using the Robert C…
VLBA Imaging of Central Engines in Radio Quiet Quasars
James S. Ulvestad, Robert R. J. Antonucci, Richard Barvainis
We have used the Very Long Baseline Array (VLBA) to image five radio-quiet quasars (RQQs) at milliarcsecond resolution, at frequencies between 1.4 and 5 GHz. These quasars have typ…
