Radiative transfer modelling of parsec-scale dusty warped discs

H. Jud, M. Schartmann, J. Mould +2

Warped discs have been found on (sub-)parsec scale in some nearby Seyfert nuclei, identified by their maser emission. Using dust radiative transfer simulations we explore their obs…

NGC 1068: No change in the mid-IR torus structure despite X-ray variability

N. López-Gonzaga, D. Asmus, F. E. Bauer +5

Context. Recent NuSTAR observations revealed a somewhat unexpected increase in the X-ray flux of the nucleus of NGC 1068. We expect the infrared emission of the dusty torus to reac…

Planet Formation Imager (PFI): science vision and key requirements

Stefan Kraus, John D. Monnier, Michael J. Ireland +75

The Planet Formation Imager (PFI) project aims to provide a strong scientific vision for ground-based optical astronomy beyond the upcoming generation of Extremely Large Telescopes…

Mid-infrared interferometry of 23 AGN tori: On the significance of polar-elongated emission

N. López-Gonzaga, L. Burtscher, K. R. W. Tristram +2

Context. Detailed high resolution studies of AGN with mid-infrared (MIR) interferometry have revealed parsec-sized dust emission elongated in the polar direction in four sources. A…

The nuclear dust lane of Circinus: collimation without a torus

M. Mezcua, M. A. Prieto, J. A. Fernández-Ontiveros +1

In some AGN, nuclear dust lanes connected to kpc-scale dust structures provide all the extinction required to obscure the nucleus, challenging the role of the dusty torus proposed…
