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…
High-Spatial Resolution SED of NGC 1068 from Near-IR to Radio. Disentangling the thermal and non-thermal contributions
Sebastian F. Hoenig, M. Almudena Prieto, Thomas Beckert
We investigate the ideas that a sizable fraction of the interferometrically unresolved infrared emission of the nucleus of NGC 1068 might originate from other processes than therma…
AGN dust tori at low and high luminosities
Sebastian F. Hoenig, Thomas Beckert
A cornerstone of AGN unification schemes is the presence of an optically and geometrically thick dust torus. It provides the obscuration to explain the difference between type 1 an…
The spectral energy distribution of the central parsec-scaled region of AGN
M. A. Prieto, J. Reunanen, Th. Beckert +4
Genuine spectral energy distributions (SEDs) of the central few parsec of the nearest and brightest active galaxies in the Southern Hemisphere are presented. They are compiled from…
3D Radiative Transfer Modeling of Clumpy Dust Tori Around AGN
S. F. Hoenig, T. Beckert, K. Ohnaka +1
We present 3-dimensional radiative transfer models for clumpy dust tori around AGN. Our method combines Monte Carlo simulations of individual dust clouds with the actual 3-dimensio…
VLTI/VINCI observations of the nucleus of NGC 1068 using the adaptive optics system MACAO
M. Wittkowski, P. Kervella, R. Arsenault +3
We present the first near-infrared K-band long-baseline interferometric measurement of the prototype Seyfert 2 galaxy NGC 1068 with resolution lambda/B \~ 10 mas obtained with the…
