We present K, L and M diffraction-limited images of NGC 1068 obtained with NAOS+CONICA at VLT/YEPUN over a 3.5" field around the central engine. Hot dust (Tcol = 550-650 K) is found in three different regions : (a) in the true nucleus, seen as a slightly NS elongated, core of extremely hot dust, "resolved" in K and L with respective diameters of ~5 pc and 8.5 pc ; (b) along the NS direction, as a "spiral arm" and a southern tongue ; (c) as a set of parallel elongatednodules ("wave-like…

Revealing the large nuclear dust structures in NGC 1068 with MIDI/VLTI

Aims. To understand the relation in AGNs between the small “obscuring torus" and dusty structures at larger scales (5-10 pc). Methods. The dusty structures in AGNs are best observed in the

Four quadrant phase mask K -band coronagraphy of NGC 1068 with NAOS-CONICA at VLT

We observed the nucleus of NGC 1068 at Ks with NAOS-CONICA on the VLT, using the new four quadrant phase mask coronagraph that we recently developed. As the K-band emission is dominated by an intense

Observing the Seyfert 2 nucleus of NGC 1068 with the VLT interferometer

Dusty tori have been suggested to play a crucial role in determining the physical characteristics of active galactic nuclei (AGN), but investigation of their properties has stalled for lack of high

The central parsecs of active galactic nuclei: challenges to the torus

Type 2 AGN are by definition nuclei in which the broad-line region and continuum light are hidden at optical/UV wavelengths by dust. Via accurate registration of infrared (IR) Very Large Telescope

Star formation and jet-induced coronal lines near the core of NGC 1068 High angular resolution near-IR spectroscopy with NaCo

Context. Active galactic nuclei (AGNs) are very luminous galaxies from the ultraviolet (UV) to the far infrared (FIR). To study regions near the core, which are dominated by dust, IR is the perfect
