DESI-Y1 and the Mystery of the Neutrino Mass

In April 2024, the Dark Energy Spectroscopic Instrument (DESI) collaboration released their first cosmological results [1]. These results made the news primarily because they showed some hints of dynamical dark energy (see the article in the same…

DESI may have initiated a paradigm shift in cosmology

DESI has made the largest 3D map of our universe to date. Earth is at the center of this thin slice of the full map. In the magnified section, it is easy to see the underlying structure of matter in our universe. Claire Lamman/DESI…
