IPNS One-Day Workshop:

DESI and related physics

Date: February 26th (Thursday) , 2026
Place: KEK Tsukuba campus, San-go-kan Building 1F Conference Room 1

This one-day workshop focuses on the latest results from the Dark Energy Spectroscopic Instrument (DESI) and their implications for cosmology. We aim to bring together researchers to discuss observational findings, theoretical interpretations, and connections to related surveys and probes. The program will also include introductory and pedagogical components intended for participants from outside the immediate DESI community and from neighboring fields. The meeting will provide a platform for exchanging ideas and fostering new collaborations within the community.
