Characterization of avalanche photodiodes (APDs) for the CUbesat Solar Polarimeter (CUSP) mission
F. Cologgi, A. Alimenti, S. Fabiani +39
The CUbesat Solar Polarimeter (CUSP) project is a CubeSat mission orbiting the Earth aimed to measure the linear polarization of solar flares in the hard X-ray band by means of a C…
Laser Guide Star uplink beam: scattering and Raman emission measurements with the 10.4m Gran Telescopio CANARIAS
G. Lombardi, D. Bonaccini Calia, M. Centrone +2
Laser Guide Star Adaptive Optics (LGS-AO) is becoming routine in several astronomical observatories. The use of powerful lasers generates sensible Raman emissions on the uplink las…
High Contrast Imaging in the Visible: First Experimental Results at the Large Binocular Telescope
F. Pedichini, M. Stangalini, A. Ambrosino +13
In February 2014, the SHARK-VIS (System for High contrast And coronography from R to K at VISual bands) Forerunner, a high contrast experimental imager operating at visible wavelen…
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…
MOONS: a Multi-Object Optical and Near-infrared Spectrograph for the VLT
M. Cirasuolo, J. Afonso, R. Bender +77
MOONS is a new conceptual design for a Multi-Object Optical and Near-infrared Spectrograph for the Very Large Telescope (VLT), selected by ESO for a Phase A study. The baseline des…
Laser guide star return-flux gain from frequency chirping
J. Hellemeier, M. Enderlein, M. Hager +7
Spectral hole burning reduces sodium laser guide star efficiency. Due to photon recoil, atoms that are initially resonant with the single-frequency laser get Doppler shifted out of…
