MUST France meeting

This week, on Thursday, April 9, and Friday, April 10, the MUST France meeting will take place in the amphitheater, organized by Eric Jullo.

The Multiplexed Spectrograph Telescope (MUST) is a fifth-generation telescope currently under construction at 4,300 meters in China. It features a 6.5-meter mirror and a system of 40 spectrographs connected to 20,000 motorized optical fibers. The goal is to measure 120 million redshifts of galaxies and stars between 2030 and 2039, aiming to test our cosmological model and improve the mapping of stars and dark matter in our galaxy.

The purpose of this meeting is to introduce the project to the French research community and to explore potential scientific and technical contributions to participate in the project and gain access to its data.
