AGN Jets from Formation to Dissipation

Anne-Kathrin Baczko, A. -K. Baczko, Eleni Vardoulaki +27

Active Galactic Nuclei (AGN) are among the most energetic phenomena in the Universe, capable of launching powerful relativistic jets that extend from sub-parsec to megaparsec scale…

VLTI/GRAVITY Interferometric Measurements of Innermost Dust Structure Sizes around AGNs

GRAVITY Collaboration, A. Amorim, G. Bourdarot +41

We present new VLTI/GRAVITY near-infrared interferometric measurements of the angular size of the innermost hot dust continuum for 14 type 1 AGNs. The angular sizes are resolved on…

The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction

Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14

The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…

The size-luminosity relation of local active galactic nuclei from interferometric observations of the broad-line region

GRAVITY Collaboration, A. Amorim, G. Bourdarot +42

By using the GRAVITY instrument with the near-infrared (NIR) Very Large Telescope Interferometer (VLTI), the structure of the broad (emission-)line region (BLR) in active galactic…

Towards measuring supermassive black hole masses with interferometric observations of the dust continuum

GRAVITY Collaboration, A. Amorim, G. Bourdarot +40

This work focuses on active galactic nuclei (AGNs), and the relation between the sizes of the hot dust continuum and the broad-line region (BLR). We find that the continuum size me…

On-sky validation of image-based adaptive optics wavefront sensor referencing

Nour Skaf, Olivier Guyon, Eric Gendron +14

Differentiating between an exoplanet signal and residual speckle noise is a key challenge in high-contrast imaging. Speckles are due to a combination of fast, slow and static wavef…
