Asgard/NOTT: L-band nulling interferometry at the VLTI. II. Warm optical design and injection system
Germain Garreau, Azzurra Bigioli, Romain Laugier +17
Asgard/NOTT (previously Hi-5) is a European Research Council (ERC)-funded project hosted at KU Leuven and a new visitor instrument for the Very Large Telescope Interferometer (VLTI…
2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Pyxis: A ground-based demonstrator for formation-flying optical interferometry
Jonah T. Hansen, Samuel Wade, Michael J. Ireland +6
In the past few years, there has been a resurgence in studies towards space-based optical/infrared interferometry, particularly with the vision to use the technique to discover and…
High-contrast detection of exoplanets with a kernel-nuller at the VLTI
Peter Marley Chingaipe, Frantz Martinache, Nick Cvetojevic +5
Context: The conventional approach to direct imaging has been the use of a single aperture coronagraph with wavefront correction via extreme adaptive optics. Such systems are limit…
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…
