ESCAPE project: testing active observing strategies for high-contrast imaging in space on the HiCAT testbed
Alexis Lau, Élodie Choquet, Lisa Altinier +6
The Roman Space Telescope will be a critical mission to demonstrate high-contrast imaging technologies allowing for the characterisation of exoplanets in reflected light. It will d…
ESCAPE project. CAPyBARA: a Roman Coronagraph simulator for post-processing methods development
Lisa Altinier, Élodie Choquet, Arthur Vigan +2
The Roman Coronagraph Instrument will be the first space facility equipped with deformable mirrors (DMs). These will lead to reach a contrast of or better in a dark hole…
ESCAPE project: fundamental detection limits of JWST/NIRCam coronographic observations
N. Godoy, E. Choquet, L. Altinier +4
In this study, we explored the fundamental contrast limit of NIRCam coronagraphy observations, representing the achievable performance with post-processing techniques. This limit i…
High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
A catalogue of dual-field interferometric binary calibrators
M. Nowak, S. Lacour, R. Abuter +97
Dual-field interferometric observations with VLTI/GRAVITY sometimes require the use of a "binary calibrator", a binary star whose individual components remain unresolved by the int…
Integrated photonic-based coronagraphic systems for future space telescopes
Niyati Desai, Lorenzo König, Emiel Por +38
The detection and characterization of Earth-like exoplanets around Sun-like stars is a primary science motivation for the Habitable Worlds Observatory. However, the current best te…
