INGOT WFS for LGSs: First Results from Simulations
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +10
The Ingot WFS, a Pyramid-like WFS, has been proposed as a relief to the LGS spot elongation. Actually, the artificial sources are confined in an excited cigar-shaped region in the…
Deep observations with an ELT in the Global Multi Conjugated Adaptive Optics perspective
Elisa Portaluri, Valentina Viotto, Roberto Ragazzoni +6
Deep observations of the Universe, usually as a part of sky surveys, are one of the symbols of the modern astronomy because they can allow big collaborations, exploiting multiple f…
Pupil plane wavefront sensing for extended and 3D sources
Roberto Ragazzoni, Valentina Viotto, Elisa Portaluri +11
The basic outline of a pupil plane WaveFront Sensor is reviewed taking into account that the source to be sensed could be different from an unresolved source, i.e. it is extended,…
INGOT Wavefront Sensor: Simulation of Pupil Images
Valentina Viotto, Elisa Portaluri, Carmelo Arcidiacono +9
The ingot wavefront sensor (I-WFS) has been proposed, for ELT-like apertures, as a possible pupil plane WFS, to cope with the geometrical characteristics of a laser guide star (LGS…
XAO-assisted coronagraphy with SHARK NIR: from simulations to laboratory tests
Gabriele Umbriaco, Elena Carolo, Daniele Vassallo +22
Several Extreme Adaptive Optics (XAO) systems dedicated to the detection and characterisation of the exoplanets are currently in operation for 8-10 meter class telescopes. Coronagr…
The hot dayside and asymmetric transit of WASP-189b seen by CHEOPS
M. Lendl, Sz. Csizmadia, A. Deline +102
The CHEOPS space mission dedicated to exoplanet follow-up was launched in December 2019, equipped with the capacity to perform photometric measurements at the 20 ppm level. As CHEO…
