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…
Entering into the Wide Field Adaptive Optics Era on Maunakea
Gaetano Sivo, John Blakeslee, Jennifer Lotz +32
As part of the National Science Foundation funded "Gemini in the Era of MultiMessenger Astronomy" (GEMMA) program, Gemini Observatory is developing GNAO, a widefield adaptive optic…
Identifying optical turbulence profiles for realistic tomographic error in adaptive optics
O. J. D. Farley, J. Osborn, T. Morris +4
For extremely large telescopes, adaptive optics will be required to correct the Earth's turbulent atmosphere. The performance of tomographic adaptive optics is strongly dependent o…
Adaptive optics with programmable Fourier-based wavefront sensors: a spatial light modulator approach to the LOOPS testbed
Pierre Janin-Potiron, Vincent Chambouleyron, Lauren Schatz +10
Wavefront sensors encode phase information of an incoming wavefront into an intensity pattern that can be measured on a camera. Several kinds of wavefront sensors (WFS) are used in…
PRIME: Psf Reconstruction and Identification for Multiple sources characterization Enhancement. Application to Keck NIRC2 imager
O. Beltramo-Martin, C. M. Correia, S. Ragland +4
In order to enhance accuracy of astrophysical estimates obtained on Adaptive-optics (AO) images, such as photometry and astrometry, we investigate a new concept to constrain the Po…
Closing the gap between Earth-based and interplanetary mission observations: Vesta seen by VLT/SPHERE
R. JL. Fétick, L. Jorda, P. Vernazza +34
Context. Over the past decades, several interplanetary missions have studied small bodies in situ, leading to major advances in our understanding of their geological and geophysica…
