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…
Optimizing the subwavelength grating of L-band Annular Groove Phase Masks for high coronagraphic performance
Ernesto Vargas Catalan, Elsa Huby, Pontus Forsberg +9
Context. The Annular Groove Phase Mask (AGPM) is one possible implementation of the vector vortex coronagraph, where the helical phase ramp is produced by a concentric subwavelengt…
Mid-IR AGPMs for ELT applications
Brunella Carlomagno, Christian Delacroix, Olivier Absil +8
The mid-infrared region is well suited for exoplanet detection thanks to the reduced contrast between the planet and its host star with respect to the visible and near-infrared wav…
The VORTEX coronagraphic test bench
Aissa Jolivet, Pierre Piron, Elsa Huby +5
In this paper, we present the infrared coronagraphic test bench of the University of Liège named VODCA (Vortex Optical Demonstrator for Coronagraphic Applications). The goal of the…
The VORTEX project: first results and perspectives
Olivier Absil, Dimitri Mawet, Christian Delacroix +15
(abridged) Vortex coronagraphs are among the most promising solutions to perform high contrast imaging at small angular separations. They feature a very small inner working angle,…
