HARMONI at ELT: Reoptimization of the NGSS natural guide star sensors system for MCAO compatibility
Kjetil Dohlen, David Le Mignant, Anne Bonnefoi +16
HARMONI is the first-light, adaptive optics assisted, near-IR integral field spectrograph for the ELT. It covers a spectral range from below 800nm to 2400nm with resolving powers f…
PRIMA: PRIMAger, a far-infrared hyperspectral and polarimetric instrument
Laure Ciesla, Charles Darren Dowell, Marc Sauvage +27
The PRobe far-Infrared Mission for Astrophysics (PRIMA) is an infrared observatory for the next decade, currently in Phase A, with a 1.8m telescope actively cooled to 4.5K. On boar…
Flux reconstruction for the NIR camera CAGIRE at the focus of the Colibrà telescope
Alix Nouvel de la Flèche, Jean-Luc Atteia, Hervé Valentin +20
CAGIRE is the near infrared camera of the Colibrà robotic telescope, designed for the follow-up of SVOM alerts. It is based on the ALFA 2k x 2k detector, from the LYNRED French Co…
The Infra-Red Telescope (IRT) on board the THESEUS mission
Diego Götz, Stéphane Basa, Frédéric Pinsard +19
The Infra-Red Telescope (IRT) is part of the payload of the THESEUS mission, which is one of the two ESA M5 candidates within the Cosmic Vision program, planned for launch in 2032.…
The detectability of high-redshift gamma-ray bursts near-infrared afterglows with CAGIRE
Francis Fortin, Jean-Luc Atteia, Alix Nouvel de la Flèche +12
Context. Transient sky astronomy is entering a new era with the advent of the SVOM mission (Space Variable Objects Monitor), which was successfully launched on the 26th of June, 20…
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…
