Over 175 researchers from around the world attended the Dark Energy Spectroscopic Instrument (DESI) 2025 Summer Collaboration Meeting at Berkeley Lab on July 8-11. The meeting was held shortly after the release of dark energy results from DESI’s first three years of data. Some of the more complex analyses of these data are still in progress, which many researchers expect will further constrain dark energy. Discussions at the meeting also included plans to combine these data with other data sets measuring gravitational lensing to further interpret how dark energy may be changing with time. Planning is also underway for a potential follow-up to DESI – the DESI-II survey – which would upgrade parts of the current instrument and include observations of a much larger sample of galaxies in the more distant universe.
