Optical gains measurement with a gain scheduling camera: On-sky demonstration with PAPYRUS and perspectives
A. Striffling, C. -T. Héritier, R. J. -L Fétick +4
Reaching the high angular resolution and contrast level desired for exoplanetary science requires us to equip large telescopes with extreme adaptive optics (XAO) systems to compens…
Improved prior for adaptive optics point spread function estimation from science images: Application for deconvolution
A. Lau, R. JL. Fétick, B. Neichel +2
Access to knowledge of the point spread function (PSF) of adaptive optics(AO)-assisted observations is still a major limitation when processing AO data. This limitation is particul…
The equilibrium shape of (65) Cybele: primordial or relic of a large impact?
M. Marsset, M. Brož, J. Vermersch +24
Cybele asteroids constitute an appealing reservoir of primitive material genetically linked to the outer Solar System, and the physical properties of the largest members can be rea…
Central kinematics of the Galactic globular cluster M80
Fabian Göttgens, Sebastian Kamann, Holger Baumgardt +7
We use spectra observed with the integral-field spectrograph MUSE to reveal the central kinematics of the Galactic globular cluster Messier 80 (M80, NGC 6093). Using observations o…
Blind deconvolution in astronomy with adaptive optics: the parametric marginal approach
Romain Fétick, Laurent Mugnier, Thierry Fusco +1
One of the major limitations of adaptive optics (AO) corrected image post-processing is the lack of knowledge on the system point spread function (PSF). The PSF is not always avail…
Physics-based model of the adaptive-optics corrected point-spread-function
Romain Fétick, Thierry Fusco, Benoit Neichel +8
Context. Adaptive optics (AO) systems greatly increase the resolution of large telescopes, but produce complex point spread function (PSF) shapes, varying in time and across the fi…
