GRAVITY faint: reducing noise sources in GRAVITY with a fast metrology attenuation system
F. Widmann, S. Gillessen, T. Ott +28
With the upgrade from GRAVITY to GRAVITY the instrument will evolve into an all-sky interferometer that can observe faint targets, such as high redshift AGN. Observing the fain…
Hypercubes of AGN Tori (HYPERCAT) -- I. Models and Image Morphology
R. Nikutta, E. Lopez-Rodriguez, K. Ichikawa +4
Near- and mid-infrared interferometers have resolved the dusty parsec-scale obscurer (torus) around nearby active galactic nuclei (AGNs). With the arrival of extremely large single…
Resolving the Hot Dust Disk of ESO323-G77
James H. Leftley, Konrad R. W. Tristram, Sebastian F. Hönig +3
Infrared interferometry has fuelled a paradigm shift in our understanding of the dusty structure in the central parsecs of Active Galactic Nuclei (AGN). The dust is now thought to…
The spatially resolved broad line region of IRAS 09149-6206
GRAVITY Collaboration, A. Amorim, W. Brandner +41
We present new near-infrared VLTI/GRAVITY interferometric spectra that spatially resolve the broad Br emission line in the nucleus of the active galaxy IRAS 09149-6206. We use t…
The role of infrared radiation pressure in shaping dusty winds in AGN
Marta Venanzi, Sebastian Hönig, David Williamson
The detection of dusty winds dominating the infrared emission of AGN on parsec scales has revealed the limitations of traditional radiative transfer models based on a toroidal dist…
Radiation hydrodynamics models of Active Galactic Nuclei: Beyond the central parsec
David Williamson, Sebastian Hönig, Marta Venanzi
We produce radiation hydrodynamics models of an AGN 'torus' plus outflow on 1-100 pc scales. This large scale permits direct comparison with observations, provides justification fo…
