Exoplanet imaging with ELTs: exploring a second-stage AO with a Zernike wavefront sensor on the ESO/GHOST testbed

Mamadou N'Diaye, Arthur Vigan, Byron Engler +6

We propose to explore a cascade extreme Adaptive optics (ExAO) approach with a second stage based on a Zernike wavefront sensor (ZWFS) for exoplanet imaging and spectroscopy. Most…

CAGIRE: a wide-field NIR imager for the COLIBRI 1.3 meter robotic telescope

Alix Nouvel de la Flèche, Jean-Luc Atteia, Jérémie Boy +32

The use of high energy transients such as Gamma Ray Bursts (GRBs) as probes of the distant universe relies on the close collaboration between space and ground facilities. In this c…
