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...

Polarimetric interferometry combines milliarcsecond angular resolution with sensitivity to scattered light and can therefore probe both dust formation around evolved stars and dust survival at the inner rims of planet-forming disks. At optical and near-infrared wavelengths, however, the many oblique reflections in an i...

The detection of Earth-like exoplanets via astrometry necessitates centroiding precision at the 0.3 microarcsec level, thereby imposing stringent constraints on the focal plane geometry of space telescopes. The AGATE focal plane instrument, a proposed component of the NASA Habitable Worlds Observatory (HWO), aims to ac...
