Executable verification through formalized expert reasoning in astronomical spectroscopy
Haosong Wang, Ting Tan, Ji Yao +5
Artificial intelligence has reshaped scientific prediction, but scientific verification remains a human bottleneck. Automated systems can map observations to labels, parameters or…
WST, the wide-field spectroscopic telescope: progress on the design of the instruments
David Lee, Joel Vernet, Elizabeth George +47
WST, the Wide-field Spectroscopic Telescope is a proposed new facility that will provide a transformational gain in spectroscopic survey capability over existing facilities. The WS…
MOSAIC at ELT: Design and First Prototyping of Novel Robotic Optical-Relay Positioners
Maxime Rombach, Markus Thurneysen, Lucas Ortolani +9
The Extremely Large Telescope (ELT) is, to date, the most ambitious ground-based telescope under construction. MOSAIC is a multi-objects spectrograph (MOS) that aims to make full u…
Focal Plate Prototyping for Modular Focal Planes of Stage-5 Instruments For Ground-Based Telescopes
Maxime Rombach, Jean-David Perriard, Laurent Chevalley +3
As current Stage-4 multi-object instruments such as SDSS-V, DESI, MOONS or 4MOST are providing astrophysicists data to study the objects of the Universe, effort is arising to build…
Streak detection in the VST/OmegaCAM archive using deep learning
Elisabeth Rachith, Stephan Hellmich, Vincent Fiszbin +3
Ground-based astronomical surveys inadvertently capture streaks from satellites and space debris crossing their fields of view. These incidental observations from wide-field instru…
Optimization of Tessellation-based Statistics: Void Statistics
Yu Liu, Cheng Zhao, Yu Yu +2
Tessellation methods are extensively employed in the analyses of cosmic large-scale structure (LSS). However, these techniques are highly sensitive to perturbations in both densiti…
