Talk Cosmology and Large-scale Structure First session

Speaker

Prof. Cheng Zhao (Tsinghua University)

Description

The Dark Energy Spectroscopic Instrument (DESI) has constructed the largest 3D map of galaxies and quasars to date, spanning the nearby Universe to a redshift of over 3. Recently, DESI has released cosmological measurements from its third-year (Y3) data, revealing evidences of dynamic dark energy. In this talk, I will review DESI results and discuss future developments.
