Possible evidence for a common radial structure in nearby AGN tori
Makoto Kishimoto, Sebastian F. Hoenig, Konrad R. W. Tristram +1
We present a quantitative and relatively model-independent way to assess the radial structure of nearby AGN tori. These putative tori have been studied with long-baseline infrared…
AGN accretion disks as spatially resolved by polarimetry
Makoto Kishimoto, Robert Antonucci, Omer Blaes +4
A crucial difficulty in understanding the nature of the putative accretion disk in AGNs is that some of its key intrinsic spectral signatures cannot be observed directly. The stron…
The characteristic blue spectra of accretion disks in quasars as uncovered in the infrared
Makoto Kishimoto, Robert Antonucci, Omer Blaes +4
Quasars are thought to be powered by supermassive black holes accreting surrounding gas. Central to this picture is a putative accretion disk which is believed to be the source of…
Discovery of a strong Baldwin effect in mid-infrared AGN lines
S. F. Hoenig, A. Smette, T. Beckert +5
We present the discovery of a Baldwin effect in 8 nearby Seyfert galaxies for the three most prominent mid-infrared forbidden emission lines observable from the ground that are com…
The innermost region of AGN tori: implications from the HST/NICMOS Type 1 point sources and near-IR reverberation
Makoto Kishimoto, Sebastian F. Hoenig, Thomas Beckert +1
Spatially resolving the innermost torus in AGN is one of the main goals of its high-spatial-resolution studies. This could be done in the near-IR observations of Type 1 AGNs where…
Resolving the BLR in NGC 3783
P. Lira, M. Kishimoto, A. Robinson +5
We present results from very high signal-to-noise spectropolarimetric observations of the Seyfert 1 galaxy NGC 3783. Position Angle (PA) changes across the Balmer lines show that t…
