Description
The 4-meter Multi-Object Spectroscopic Telescope (4MOST) is a fibre-fed spectroscopic instrument installed on the VISTA telescope in Chile. It will simultaneously measure ~2400 spectra of objects on the sky and aims to study a wide range of astrophysical sciences from galactic science cases to cosmology with large scale structures. In this talk, I will present the current status of 4MOST, which is scheduled to begin observations in early 2025, focusing on the 4MOST-Cosmological Redshidt Survey (CRS), which plans to map ~8 million galaxy quasars observed down to redshift z ~ 3.5.
