Recent observations of NGC 1068 and other AGN support the idea of a geometrically and
optically thick dust torus surrounding the central supermassive black hole and accretion disk …

With the possibilities of high spatial resolution imaging and spectroscopy as well as infrared
(IR) interferometry, the dusty environments (= “dusty torus”) of active galactic nuclei (AGN) …

Context. The AGN-heated dust distribution (the “torus”) is increasingly recognized not only
as the absorber required in unifying models, but as a tracer for the reservoir that feeds the …

… With more than a factor of two variability in the near-IR, it is plausible that we may also detect
variability in the mid-IR (H�nig & Kishimoto 2011). We initiated an IR monitoring campaign …

Context. With infrared interferometry it is possible to resolve the nuclear dust distributions that
are commonly associated with the dusty torus in active galactic nuclei (AGN). The Circinus …

Spatially resolving the innermost region of the putative torus-like structure in an active galactic
nucleus (AGN) is one of the main goals of high-spatial-resolution studies. This could be …

We present an updated mid-infrared (MIR) versus X-ray correlation for the local active galactic
nuclei (AGN) population based on the high angular resolution 12 and 18μm continuum …

We present the first subarcsecond-resolution mid-infrared (MIR) atlas of local active galactic
nuclei (AGN). Our atlas contains 253 AGN with a median redshift of z = 0.016, and includes …

In the Spring of 2011 we carried out a 2.5 month reverberation mapping campaign using the
3 m Shane telescope at Lick Observatory, monitoring 15 low-redshift Seyfert 1 galaxies. …

… This indicates that the SF activity per unit area in the central ∼65 pc region of Seyfert
galaxies is much higher than at larger distances from their nuclei. We studied the�…
