Exomoon search with VLTI/GRAVITY around the substellar companion HD 206893 B

Q. Kral, J. Wang, J. Kammerer +130

Direct astrometric detection of exomoons remains unexplored. This study presents the first application of high-precision astrometry to search for exomoons around substellar compani…

First Light for the GRAVITY+ Adaptive Optics: Extreme Adaptive Optics for the Very Large Telescope Interferometer

GRAVITY+ Collaboration, :, F. Allouche +137

GRAVITY+ improves by orders of magnitude the sensitivity, sky-coverage and contrast of the Very Large Telescope Interferometer (VLTI). A central part of this project is the develop…

Spatially resolved broad line region in a quasar at z=4: Dynamical black hole mass and prominent outflow

GRAVITY+ Collaboration, K. Abd El Dayem, N. Aimar +92

We present the first near-infrared interferometric data of a QSO at z=4. The K-band observations were performed with GRAVITY+ on the VLTI using all four UTs, detecting a differenti…

The mid-infrared spectrum of Pictoris b. First VLTI/MATISSE interferometric observations of an exoplanet

M. Houllé, F. Millour, P. Berio +46

Few spectra of directly-imaged exoplanets have been obtained in the mid-infrared (> 3 m). This region is particularly rich in molecular spectral signatures, whose measurements c…

First Resolution of Microlensed Images of a Binary-Lens Event

Zexuan Wu, Subo Dong, A. Mérand +72

We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves sh…
