"The Need for High Spectral Resolution in Future Spectroscopic Surveys"
ESO Informal Discussion
- Date: Apr 22, 2026
- Time: 10:00 AM - 11:00 AM (Local Time Germany)
- Speaker: Tadafumi Matsuno (ARI-ZAH, Heidelberg University)
- Location: ESO Garching
- Room: Library
Abstract:
Spectroscopic surveys have been providing invaluable data in the field of Galactic archaeology and nucleosynthesis. While we are about to witness another revolution in the field with the start of 4MOST this year, we have already started to think about the next generations of spectroscopic survey facilities. In this talk, I will introduce the concept of the wide-field spectroscopic telescope (WST), which is planned for 2040s. I will discuss the need for equipping the WST with a higher spectral resolution spectrograph than the current generation of surveys, and how it can open new windows to study the origin of the elements and stellar populations in the Milky Way.
