The central dusty torus in the active nucleus of NGC 1068
TLDR
Interferometric mid-infrared observations that spatially resolve dust structures in the galaxy NGC 1068 reveal warm dust in a structure 2.1 parsec thick and 3.4 parsec in diameter, surrounding a smaller hot structure.

The dusty heart of nearby active galaxies - I. High-spatial resolution mid-IR spectro-photometry of Seyfert galaxies
In a series of papers, we aim at stepping towards characterizing physical properties of the AGN dust torus by combining IR highspatial resolution observations with 3D clumpy torus models. In this…

The innermost region of AGN tori: implications from the HST/NICMOS type 1 point sources and near-IR reverberation
Spatially resolving the innermost region of the putative torus-like structure in an active galactic nucleus (AGN) is one of the main goals of high-spatial-resolution studies. This could be done in…

A diversity of dusty AGN tori - Data release for the VLTI/MIDI AGN Large Program and first results for 23 galaxies
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 nuclear Super-Massive…

A hot compact dust disk around a massive young stellar object
TLDR
Near-infrared interferometric observations that spatially resolve the astronomical-unit-scale distribution of hot material around a high-mass (∼20 solar masses) young stellar object show an elongated structure with a size of ∼13 × 19 astronomical units, consistent with a disk seen at an inclination angle of ∼45°.

Tracing the young massive high-eccentricity binary system Theta 1 Orionis C through periastron passage
Context. The nearby high-mass star binary system θ 1 Ori C is the brightest and most massive of the Trapezium OB stars at the core of the Orion Nebula Cluster, and it represents a perfect laboratory…

Constraining the structure of the planet-forming region in the disk of the Herbig Be star HD 100546 ?
Studying the physical conditions in circumstellar disks is a crucial step toward understanding planet formation. Of particular interest is the case of HD 100546, a Herbig Be star that presents a gap…

Mid-infrared sizes of circumstellar disks around Herbig Ae/Be stars measured with MIDI on the VLTI
We present the first long baseline mid-infrared interferometric observations of the circumstellar disks surrounding Herbig Ae/Be stars. The observations were obtained using the mid-infrared…
