Upgrading the high contrast imaging facility SPHERE: science drivers and instrument choices
A. Boccaletti, G. Chauvin, F. Wildi +71
SPHERE+ is a proposed upgrade of the SPHERE instrument at the VLT, which is intended to boost the current performances of detection and characterization for exoplanets and disks. S…
High contrast imaging wavefront sensor referencing from coronagraphic images
Nour Skaf, Olivier Guyon, Anthony Boccaletti +11
A key challenge of high contrast imaging (HCI) is to differentiate a speckle from an exoplanet signal. The sources of speckles are a combination of atmospheric residuals and aberra…
On-sky validation of image-based adaptive optics wavefront sensor referencing
Nour Skaf, Olivier Guyon, Eric Gendron +14
Differentiating between an exoplanet signal and residual speckle noise is a key challenge in high-contrast imaging. Speckles are due to a combination of fast, slow and static wavef…
MICADO PSF-Reconstruction work package description
Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +25
The point spread function reconstruction (PSF-R) capability is a deliverable of the MICADO@ESO-ELT project. The PSF-R team works on the implementation of the instrument software de…
SPHERE+: Imaging young Jupiters down to the snowline
A. Boccaletti, G. Chauvin, D. Mouillet +130
SPHERE (Beuzit et al,. 2019) has now been in operation at the VLT for more than 5 years, demonstrating a high level of performance. SPHERE has produced outstanding results using a…
On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
A. G. Basden, L. Bardou, D. Bonaccini Calia +18
The performance of adaptive optics systems is partially dependant on the algorithms used within the real-time control system to compute wavefront slope measurements. We demonstrate…
