Thermal imaging of dust hiding the black hole in the Active Galaxy NGC 1068

Violeta Gamez Rosas, Jacob W. Isbell, Walter Jaffe +49

In the widely accepted 'Unified Model' solution of the classification puzzle of Active Galactic Nuclei, the orientation of a dusty accretion torus around the central black hole dom…

The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE

A. Chiavassa, K. Kravchenko, M. Montargès +50

Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…

VLTI-MATISSE L- and N-band aperture-synthesis imaging of the unclassified B[e] star FS Canis Majoris

K. -H. Hofmann, A. Bensberg, D. Schertl +58

Context: FS Canis Majoris (FS CMa, HD 45677) is an unclassified B[e] star surrounded by an inclined dust disk. The evolutionary stage of FS CMa is still debated. Perpendicular to t…

Stellar populations in local AGNs: evidence for enhanced star formation in the inner 100pc

L. G. Dahmer-Hahn, R. Riffel, A. Rodríguez-Ardila +7

In modern models and simulations of galactic evolution, the star formation in massive galaxies is regulated by an ad hoc active galactic nuclei (AGN) feedback process. However, the…

Lessons learned from SPHERE for the astrometric strategy of the next generation of exoplanet imaging instruments

A. -L. Maire, M. Langlois, P. Delorme +14

Measuring the orbits of directly-imaged exoplanets requires precise astrometry at the milliarcsec level over long periods of time due to their wide separation to the stars ($\gtrsi…

The Galaxy Activity, Torus and Outflow Survey (GATOS): II. Torus and polar dust emission in nearby Seyfert galaxies

A. Alonso-Herrero, S. García-Burillo, S. F. Hoenig +30

We compare mid-IR and ALMA far-IR images of 12 nearby Seyferts selected from GATOS. The mid-IR unresolved emission contributes more than 60% of the nuclear emission in most galaxie…
