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…

Polarization analysis of the VLTI and GRAVITY

GRAVITY Collaboration, F. Widmann, X. Haubois N. Schuhler +59

The goal of this work is to characterize the polarization effects of the VLTI and GRAVITY. This is needed to calibrate polarimetric observations with GRAVITY for instrumental effec…

The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits

GRAVITY Collaboration, R. Abuter, N. Aimar +62

The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…
