VLTI Unit Telescope coudé train vibration control upgrade for GRAVITY+ Open
Scaling up interferometry to 8m collectors should smooth-out the optical\npiston perturbations and allow a slow fringe tracker to obtain high precision\ncorrection on faint targets. In practice, the GRAVITY fringe tracker still\nobserves h…

The GRAVITY+ Project: Towards All-sky, Faint-Science, High-Contrast Near-Infrared Interferometry at the VLTI Open
The GRAVITY instrument has been revolutionary for near-infrared interferometry by pushing sensitivity and precision to previously unknown limits. With the upgrade of GRAVITY and the Very Large Telescope Interferometer (VLTI) in GRAVITY+, t…

The ExoGRAVITY project: using single mode interferometry to characterize exoplanets Open
Combining adaptive optics and interferometric observations results in a considerable contrast gain compared to single-telescope, extreme AO systems. Taking advantage of this, the ExoGRAVITY project is a survey of known young giant exoplane…
Infrared interferometry to spatially and spectrally resolve jets in X-ray binaries Open
Infrared interferometry is a new frontier for precision ground-based observing, with new instrumentation achieving milliarcsecond (mas) spatial resolutions for faint sources, along with astrometry on the order of 10 microarcseconds (μas). …
Bringing the New Adaptive Optics Module for Interferometry (NAOMI) into Operation Open
NAOMI was developed by a consortium composed of IPAG and ESO. Its Provisional Acceptance Chile review was held in April 2019. The NAOMI systems that have been installed on the Auxiliary Telescopes make the Very Large Telescope Interferomet…
First Light for GRAVITY: A New Era for Optical Interferometry Open
With the arrival of the second generation instrument GRAVITY, the Very Large Telescope Interferometer (VLTI) has entered a new era of optical interferometry. This instrument pushes the limits of accuracy and sensitivity by orders of magnit…
