The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
Shoko Jin, Scott C. Trager, Gavin B. Dalton +212
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree…
Asgard/NOTT: L-band nulling interferometry at the VLTI I. Simulating the expected high-contrast performance
Romain Laugier, Denis Defrère, Benjamin Courtney-Barrer +13
Context: NOTT (formerly Hi-5) is a new high-contrast L' band (3.5-4.0 \textmu m) beam combiner for the VLTI with the ambitious goal to be sensitive to young giant exoplanets down t…
A simulator-based autoencoder for focal plane wavefront sensing
Maxime Quesnel, Gilles Orban de Xivry, Olivier Absil +1
Instrumental aberrations strongly limit high-contrast imaging of exoplanets, especially when they produce quasistatic speckles in the science images. With the help of recent advanc…
Precise near-infrared photometry, accounting for precipitable water vapour at SPECULOOS Southern Observatory
Peter P. Pedersen, C. A. Murray, D. Queloz +20
The variability induced by precipitable water vapour (PWV) can heavily affect the accuracy of time-series photometric measurements gathered from the ground, especially in the near-…
Impact of water vapor seeing on mid-infrared high-contrast imaging at ELT scale
Olivier Absil, Christian Delacroix, Gilles Orban de Xivry +9
The high-speed variability of the local water vapor content in the Earth atmosphere is a significant contributor to ground-based wavefront quality throughout the infrared domain. U…
A deep learning approach for focal-plane wavefront sensing using vortex phase diversity
M. Quesnel, G. Orban de Xivry, G. Louppe +1
The performance of high-contrast imaging instruments is limited by wavefront errors, in particular by non-common path aberrations (NCPAs). Focal-plane wavefront sensing (FPWFS) is…
