A Compact Jet at the Infrared Heart of the Prototypical Low-Luminosity AGN in NGC 1052
J. A. Fernández-Ontiveros, N. López-Gonzaga, M. A. Prieto +4
The feeble radiative efficiency characteristic of Low-Luminosity Active Galactic Nuclei (LLAGN) is ascribed to a sub-Eddington accretion rate, typically at $\log(L_{\rm bol}/L_{\rm…
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…
Mid-infrared interferometry of Seyfert galaxies: Challenging the Standard Model
N. López-Gonzaga, W. Jaffe
Aims: We aim to find torus models that explain the observed high-resolution mid-infrared (MIR) measurements of active galactic nuclei (AGN). Our goal is to determine the general pr…
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…
Revealing the large nuclear dust structures in NGC 1068 with MIDI/VLTI
N. López-Gonzaga, W. Jaffe, L. Burtscher +2
To understand the relation between the small "obscuring torus" and dusty structures at larger scales (5-10 pc) in NGC 1068, we use ESO's Mid-Infrared Interferometer (MIDI) with the…
