VLTI system upgrades: recent engineering progress and future developments

Over the past six years, the VLTI has undergone major upgrades, significantly improving its stability, sensitivity, and operational reliability. This has enabled the highest-angular-resolution images of stars orbiting our Galactic Center, high-precision interferometric astrometric measurements of exoplanet systems, and...

GRAVITY+ at the VLTI: instrumental advances enabling high-angular-resolution AGN science

We present an overview of how recent and upcoming GRAVITY+ upgrades at the VLTI interconnect instrument and science, enabling high-angular-resolution studies of active galactic nuclei (AGN). Improvements such as wideangle off-axis fringe tracking, enhanced fringe-tracker performance, and state-of-the-art adaptive optic...
