Description
Two of the world's most advanced cosmological surveys, DESI (Dark Energy Spectroscopic Instrument) and DES (Dark Energy Survey), are challenging the LCDM model of cosmology. Their new results, recently released, in combination with CMB and other measurements, suggest a time-varying dark energy. In this talk, we will review the most recent DES and DESI results and their implications for the properties of the mysterious dark energy.
