Tracing the early Milky Way thin disc with the Gaia-ESO Survey
Carlos Viscasillas Vázquez, Sofia Randich, Riano Escate Giribaldi +3
The origin of metal-poor stars on thin-disc-like orbits remains an open question in Galactic archaeology and provides important constraints on the earliest phases of Milky Way disc…
WST instrument Exposure Time Calculator: full simulation of multi-mode spectrograph performance from source to detector
Matteo Ferro, Matteo Genoni, Henri M. J. Boffin +13
We present a comprehensive Exposure Time Calculator (ETC) developed for the Wide-field Spectroscopic Telescope (WST) concept. The WST, currently in its conceptual phase, is designe…
HRMOS: a very high-resolution, multi-object spectrograph for the ESO VLT
Andrea Bianco, Sofia Randich, Emma Fernandez Alvar +7
HRMOS (High-Resolution Multi-Object Spectrograph) is a proposed new instrument for the ESO Very Large Telescope (VLT) developed in the context of the ESO VLT Beyond 2030 call. It i…
Sustainability as a design parameter in the early development of the Wide-field Spectroscopic Telescope
L. Fréour, E. Burtin, R. Bacon +13
The paper describes how sustainability is being incorporated into the early design of the Wide-field Spectroscopic Telescope by using life‑cycle assessments to evaluate the carbon…
