Setup and performance of focal-plane characterization benches for high precision astrometry
Fabrice Pancher, Sebastien Soler, Fabien Malbet +7
Detecting Earth-like exoplanets requires micro-arcsecond astrometry, which relies on a precisely calibrated focal plane equipped with high-resolution detectors. Accurate calibratio…
Calibrations for high precision differential astrometry onboard Theia and HWO
Manon Lizzana, Fabien Malbet, Hugo Rousset +3
Future space astrometry missions such as Theia and an astrometric mode of the Habitable Worlds Observatory (HWO) require detector calibration and instrumental characterization at a…
Pixel-Level Calibration for Space-Based High Precision Astrometry Using Young's Fringes
Hugo Rousset, Eric Thiébaut, Chloé Rey +8
The detection of Earth-like exoplanets via astrometry necessitates centroiding precision at the 0.3 microarcsec level, thereby imposing stringent constraints on the focal plane geo…
Very High Precision Astrometry for Exoplanets and Dark Matter with the Habitable Worlds Observatory
Fabien Malbet, J. Amiaux, F. Ardellier-Desages +19
Astrometry, one of the oldest branches of astronomy, has been revolutionized by missions like Hipparcos and especially Gaia, which mapped billions of stars with extraordinary preci…
Experimental tests of the calibration of high precision differential astrometry for HWO
Manon Lizzana, Fabien Malbet, Alain Leger +7
Many different scientific applications require sub-micro arcsecond precision astrometry, including researching rocky exoplanets in the vicinity of the Sun and studying dark matter.…
Experimental tests of the calibration of high precision differential astrometry for exoplanets
Manon Lizzana, Fabien Malbet, Pierre Kern +4
High precision differential Astrometry is the branch of astronomy that evaluates the relative position, distance and motion of celestial objects with respect to the stars present i…
Laboratory characterisation bench for high precision astrometry
Fabrice Pancher, Sebastien Soler, Fabien Malbet +4
High precision differential astrometry assesses the positions, distances, and motions of celestial objects in relation to the stars. The focal plane of such space telescope must be…
Challenges in focal plane and telescope calibration for High-Precision Space Astrometry
F. Malbet, M. Lizzana, F. Pancher +10
With sub-microarcsecond angular accuracy, the \theia telescope will be capable of revealing the architectures of nearby exoplanetary systems down to the mass of Earth. This researc…
