High-contrast imaging of Galactic Cepheids with VLT/SPHERE
A. Gallenne, P. Kervella, N. R. Evans +10
Cepheids are key distance indicators and benchmarks for stellar evolution, yet most of them are members of binary or multiple systems. While spectroscopic surveys and Gaia proper-m…
Operational forecast of the PSF figures of merit
A. Turchi, G. Agapito, E. Masciadri +6
The optimization and scheduling of scientific observations done with instrumentation supported by adaptive optics could greatly benefit from the forecast of PSF figures of merit (F…
Pushing Point spread function reconstruction to the next level. Application to SPHERE/ZIMPOL
Olivier Beltramo-Martin, Antonino Marasco, Thierry Fusco +4
Point spread function (PSF) reconstruction (PSF-R) is a well established technique to determine reliably and accurately the PSF from Adaptive Optics (AO) control loop data. We have…
Successful application of PSF-R techniques to the case of the globular cluster NGC6121 (M4)
D. Massari, A. Marasco, O. Beltramo-Martin +4
Precise photometric and astrometric measurements on astronomical images require an accurate knowledge of the Point Spread Function (PSF). When the PSF cannot be modelled directly f…
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…
