ESO-VLT BlueMUSE instrument - Conceptual Design for Phase A
Florence Laurent, Johan Richard, Rémi Giroud +23
BlueMUSE is a blue-optimised, medium spectral resolution, panoramic integral field spectrograph under development for the ESO's Very Large Telescope (VLT). The project is now enter…
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…
Performance Testing of a Trillium-based 21-Positioner Module for Stage-5 Telescopes
Oliver Pineda Suárez, Jonathan Wei, Malak Galal +4
Evaluating the performance metrics of theta-phi robotic positioners is crucial to gather insights into the system's behavior and ensure their reliability during operation in Stage-…
Thermal Characterization of a 6-Positioner, 6.2-mm-Pitch Module for Stage-5 Telescopes
Maxime Rombach, Malak Galal, Jonathan Wei +3
Ensuring thermal stability of robotic fiber positioners is essential for reliable operation in the real environments of Stage-5 telescopes, where temperature variations can influen…
Comparative Study of Hollow-Core and Standard Optical Fibers for Astronomy
Malak Galal, Oliver Pineda Suárez, Frédéric Gérôme +3
Efficient light transmission in the blue-visible regime remains a major limitation for fiber-fed astronomical spectrographs, where low photon flux and the intrinsic attenuation of…
