I2C@2024: an interferometric imaging contest in 2024

Florentin Millour, Mathis Houll{é}, Jeremy Perdigon +6

Images in optical long-baseline interferometry have seen a boost in the recent years thanks to new techniques and recipes invented by the community. These images are more and more…

MATISSE in the era of GRAVITY+

Florentin Millour, Anthony Soulain, St{é}phane Lagarde +28

MATISSE, the mid-infrared spectro-interferometric imager of the Very Large Telescope Interferometer (VLTI), has been feeding on the light corrected by the GRAVITY+ Adaptive Optics…

Improving constraints on the Yukawa correction at the Galactic Center with multiple stellar orbits

GRAVITY+ Collaboration, :, A. Foschi +78

We investigate the presence of a Yukawa-like correction () to Newtonian gravity at the Galactic Center, using a multi-star fitting code, including the newly…

CO and potential variability in Pictoris b with GRAVITY+

Antonia von Stauffenberg, Jonas Sauter, Paul Mollière +18

The CO/CO ratio was introduced as an indicator for where in the disk a planet has formed. Previously a lower value compared to the host star's was suggested to show t…

GRAVITY+ adaptive optics (GPAO) tests in Europe

Florentin Millour, Guillaume Bourdarot, Jean-Baptiste Le Bouquin +54

We present in this proceeding the results of the test phase of the GRAVITY+ adaptive optics. This extreme AO will enable both high-dynamic range observations of faint companions (i…

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…
