A diversity of dusty AGN tori: Data release for the VLTI/MIDI AGN Large Program and first results for 23 galaxies
Leonard Burtscher, Klaus Meisenheimer, Konrad R. W. Tristram +9
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 nuc…
The complexity of parsec-scaled dusty tori in AGN
K. R. W. Tristram, M. Schartmann, L. Burtscher +5
Warm gas and dust surround the innermost regions of active galactic nuclei (AGN). They provide the material for accretion onto the super-massive black hole and they are held respon…
On the size-luminosity relation of AGN dust tori in the mid-infrared
Konrad R. W. Tristram, Marc Schartmann
Interferometric measurements in the mid-infrared have shown that the sizes of the warm dust distributions in active galactic nuclei are consistent with their scaling with the squar…
The Role of Secular Evolution in the Black Hole Growth of Narrow-Line Seyfert 1 Galaxies
G. Orban de Xivry, R. Davies, M. Schartmann +5
Narrow-Line Seyfert 1 (NLS1) galaxies show extreme properties with respect to the other Seyfert galaxies. Indeed, they are thought to be accreting at Eddington rates and to possess…
Radiation feedback on dusty clouds during Seyfert activity
Marc Schartmann, Martin Krause, Andreas Burkert
We investigate the evolution of dusty gas clouds falling into the centre of an active Seyfert nucleus. Two-dimensional high-resolution radiation hydrodynamics simulations are perfo…
Stability of Cloud Orbits in the Broad Line Region of Active Galactic Nuclei
Martin Krause, Andreas Burkert, Marc Schartmann
We investigate the global dynamic stability of spherical clouds in the Broad Line Region (BLR) of Active Galactic Nuclei (AGN), exposed to radial radiation pressure, gravity of the…
