The HOSTS Survey for Exozodiacal Dust: Preliminary results and future prospects
S. Ertel, G. M. Kennedy, D. Defrère +40
[abridged] The presence of large amounts of dust in the habitable zones of nearby stars is a significant obstacle for future exo-Earth imaging missions. We executed an N band nulli…
Data processing on simulated data for SHARK-NIR
E. Carolo, D. Vassallo, J. Farinato +22
A robust post processing technique is mandatory to analyse the coronagraphic high contrast imaging data. Angular Differential Imaging (ADI) and Principal Component Analysis (PCA) a…
SHARK-NIR, the coronagraphic camera for LBT, moving toward construction
Jacopo Farinato, Francesca Bacciotti, Carlo Baffa +37
SHARK-NIR is one of the two coronagraphic instruments proposed for the Large Binocular Telescope. Together with SHARK-VIS (performing coronagraphic imaging in the visible domain),…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
Status of MagAO and review of astronomical science with visible light adaptive optics
Laird M. Close, Jared R. Males, Katie M. Morzinski +10
We review astronomical results in the visible (lambda <1 micron) with adaptive optics and note the status the MagAO system and the recent upgrade to visible camera's Simultaneous/S…
Shack-Hartmann wavefront sensor sensitivity loss factor estimation in partial correction regime
Guido Agapito, Carmelo Arcidiacono, Simone Esposito
In typical adaptive optics applications, the atmospheric residual turbulence affects the wavefront sensor response decreasing its sensitivity. On the other hand, wavefront sensors…
LBT/ARGOS adaptive optics observations of z lensed galaxies
M. Perna, M. Curti, G. Cresci +24
Gravitationally lensed systems allow a detailed view of galaxies at high redshift. High spatial- and spectral-resolution measurements of arc-like structures can offer unique constr…
The HOSTS survey - Exozodiacal dust measurements for 30 stars
S. Ertel, D. Defrère, P. Hinz +40
The HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey searches for dust near the habitable zones (HZs) around nearby, bright main sequence stars. We use nulling…
