Resolving the mid-infrared cores of local Seyferts
We present new photometry of 16 local Seyferts including 6 Compton-thick sources in N -band filters around 12- μ m, obtained with the VISIR instrument on the 8-m Very Large Telescope. The…

We present the first systematic study of (non-radio-selected) radio-loud narrow-line Seyfert 1 (NLS1) galaxies. Cross-correlation of the Catalogue of Quasars and Active Nuclei with several radio and…
Ram Pressure Stripping and Galaxy Orbits: The Case of the Virgo Cluster
- B. Vollmer, V. Cayatte, C. Balkowski, W. Duschl

We investigate the role of ram pressure stripping in the Virgo Cluster using N-body simulations. Radial orbits within the Virgo Cluster's gravitational potential are modeled and analyzed with respect…
The dusty heart of nearby active galaxies - I. High-spatial resolution mid-IR spectro-photometry of Seyfert galaxies
- S. Hoenig, M. Kishimoto, G. Weigelt
- Physics
- 3 March 2010
In a series of papers, we aim at stepping towards characterizing physical properties of the AGN dust torus by combining IR highspatial resolution observations with 3D clumpy torus models. In this…
The subarcsecond mid-infrared view of local active galactic nuclei – II. The mid-infrared–X-ray correlation
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 18?m continuum fluxes from the AGN…
The subarcsecond mid-infrared view of local active galactic nuclei – I. The N- and Q-band imaging atlas
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 all publicly…

The mid IR - hard X-ray correlation in AGN and its implications for dusty torus models ,
Aims. We investigate mid-infrared and X-ray properties of the dusty torus invoked in the unification scenario for active galactic nuclei by using the relation between mid IR and hard X-ray…
The small dispersion of the mid IR - hard X-ray correlation in active galactic nuclei
Context. We investigate mid-infrared and X-ray properties of the dusty torus in unification scenarios for active galactic nuclei. Aims. We use the relation between mid IR and hard X-ray luminosities…
