The GLINT nulling interferometer: improving nulls for high-contrast imaging
Eckhart Spalding, Elizabeth Arcadi, Glen Douglass +13
GLINT is a nulling interferometer downstream of the SCExAO extreme-adaptive-optics system at the Subaru Telescope (Hawaii, USA), and is a pathfinder instrument for high-contrast im…
Asgard/NOTT: water vapor and CO atmospheric dispersion compensation system
Romain Laugier, Denis Defrère, Michael Ireland +8
To leverage the angular resolution of interferometry at high contrast, one must employ specialized beam-combiners called interferometric nullers. Nullers discard part of the astrop…
Generic data reduction for nulling interferometry package: the grip of a single data reduction package on all the nulling interferometers
Marc-Antoine Martinod, Denis Defrère, Romain Laugier +5
Nulling interferometry is a powerful observing technique to reach exoplanets and circumstellar dust at separations too small for direct imaging with single-dish telescopes and too…
Asgard/NOTT: First lab assembly and experimental results
G. Garreau, A. Bigioli, R. Laugier +17
Asgard/NOTT is an ERC-funded project hosted at KU Leuven and is part of a new visitor instrumental suite, called Asgard, under preparation for the Very Large Telescope Interferomet…
Pushing high angular resolution and high contrast observations on the VLTI from Y to L band with the Asgard instrumental suite: integration status and plans
Marc-Antoine Martinod, Denis Defrère, Michael J. Ireland +35
ESO's Very Large Telescope Interferometer has a history of record-breaking discoveries in astrophysics and significant advances in instrumentation. The next leap forward is its new…
L-band nulling interferometry at the VLTI with Asgard/NOTT: status and plans
Denis Defrère, Romain Laugier, Marc-Antoine Martinod +43
NOTT (formerly Hi-5) is the L'-band (3.5-4.0~microns) nulling interferometer of Asgard, an instrument suite in preparation for the VLTI visitor focus. The primary scientific object…
CHARA/Silmaril Instrument Software and Data Reduction Pipeline: Characterization of the Instrument in the Lab and On-Sky
Narsireddy Anugu, Theo A. ten brummelaar, Cyprien Lanthermann +9
The newly installed Silmaril beam combiner at the CHARA array is designed to observe previously inaccessible faint targets, including Active Galactic Nuclei and T-Tauri Young Stell…
Observing the Galactic Underworld: Predicting photometry and astrometry from compact remnant microlensing events
David Sweeney, Peter Tuthill, Alberto Krone-Martins +3
Isolated black holes (BHs) and neutron stars (NSs) are largely undetectable across the electromagnetic spectrum. For this reason, our only real prospect of observing these isolated…
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…
