MAVIS: Enabling High-Precision Ground-Based Astrometry in the Visible Spectrum
Mojtaba Taheri, Jesse Cranney, Antonino Marasco +9
MAVIS (the MCAO-Assisted Visible Imager and Spectrograph), planned for the VLT Adaptive Optics Facility, represents an innovative step in Multi-Conjugate Adaptive Optics (MCAO) sys…
AI-Powered Low-Order Focal Plane Wavefront Sensing in Infrared
Mojtaba Taheri, Mahdiyar Molahasani, Sam Ragland +2
Adaptive optics (AO) systems are crucial for high-resolution astronomical observations by compensating for atmospheric turbulence. While laser guide stars (LGS) address high-order…
Performance comparison of the Shack-Hartmann and pyramid wavefront sensors with a laser guide star for 40 m telescopes
Francisco Oyarzun, Cedric-Taissir Heritier, Vincent Chambouleyron +3
Context. The new giant segmented mirror telescopes will use laser guide stars (LGS) for their adaptive optics (AO) systems. Two options to use as wavefront sensors (WFS) are the Sh…
RISTRETTO: reflected-light exoplanet spectroscopy at the diffraction limit of the VLT
Christophe Lovis, Nicolas Blind, Bruno Chazelas +28
RISTRETTO is a visible high-resolution spectrograph fed by an extreme adaptive optics (AO) system, to be proposed as a visitor instrument on ESO VLT. The main science goal of RISTR…
ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
Striving towards robust phase diversity on-sky: Implementing LIFT for VLT/MUSE-NFM
Arseniy Kuznetsov, Sylvain Oberti, Benoit Neichel +1
The recent IRLOS upgrade for VLT/MUSE narrow field mode (NFM) introduced a full-pupil mode to enhance sensitivity and sky coverage. This involved replacing the 2x2 Shack-Hartmann s…
