Asgard/NOTT: L-band nulling interferometry at the VLTI I. Simulating the expected high-contrast performance
Romain Laugier, Denis Defrère, Benjamin Courtney-Barrer +13
Context: NOTT (formerly Hi-5) is a new high-contrast L' band (3.5-4.0 \textmu m) beam combiner for the VLTI with the ambitious goal to be sensitive to young giant exoplanets down t…
Towards a Better Understanding of OPD Limitations for Higher Sensitivity and Contrast at the VLTI
Benjamin Courtney-Barrer, Julien Woillez, Romain Laugier +9
Precise control of the optical path differences (OPD) in the Very Large Telescope Interferometer (VLTI) was critical for the characterization of the black hole at the center of our…
L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans
Denis Defrère, Azzurra Bigioli, Colin Dandumont +34
Hi-5 is the L'-band (3.5-4.0 m) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast a…
First Light for GRAVITY Wide: Large Separation Fringe Tracking for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, R. Abuter +114
GRAVITY+ is the upgrade of GRAVITY and the Very Large Telescope Interferometer (VLTI) with wide-separation fringe tracking, new adaptive optics, and laser guide stars on all four 8…
