Mid-IR Water-Vapor Seeing: Implications for ELT/METIS High-Contrast Imaging from VLTI Data
Abhirami S Raghu, Prashant Pathak, Olivier Absil +7
Direct imaging and characterization of rocky exoplanets remains one of the central challenges in exoplanetary science. The mid-infrared (mid-IR) offers a favorable high-contrast im…
Pre-shipment optical characterization of the SCALES instrument
Isabel J. Kain, Reni Kupke, Daren Dillon +31
The Slicer Combined with an Array of Lenslets for Exoplanet Spectroscopy (SCALES) instrument is a 1-5 micron imager and 2-5 micron integral field spectrograph, currently being comm…
GRIP: a generic data reduction package for nulling interferometry
Marc-Antoine Martinod, Denis Defrere, Romain Laugier +4
Nulling interferometry is a powerful observing technique to study exoplanets and circumstellar dust at separations too small for direct imaging with single-dish telescopes. With re…
Advancing European High-Contrast Imaging R&D Towards the Habitable Worlds Observatory
Iva Laginja, Óscar Carrión-González, Romain Laugier +31
The Habitable Worlds Observatory (HWO) will enable a transformative leap in the direct imaging and characterization of Earth-like exoplanets. For this, NASA is focusing on early in…
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…
