Alongside this release, we have also released two new value-added catalogues supplementing the older Data Release 1 announced in March.

These datasets, available ahead of the full DR2 release, include the MCMC cosmology chains used to infer cosmological parameters, along with best-fit values and supporting information. They allow researchers everywhere to reproduce DESI’s results and explore new analyses.

To mark the publication of the first DESI DR2 BAO cosmology papers in Physical Review D, the DESI Collaboration has released the full set of cosmology chains and data products supporting these results.

✨ The award includes an invited prize lecture at the 247th AAS meeting in Phoenix. DESI member Daniel Eisenstein will accept on behalf of the collaboration and deliver the closing plenary on 8 January 2026.

This annual award recognizes highly meritorious work in astronomy. The 2026 prize honors DESI for two landmark papers published this year:
🔹 February 2025: BAO results from DESI’s DR1 data.
🔹 March 2025: BAO results from 14 million galaxies and quasars observed in DESI DR2.

DESI scientists propose non-singular black holes convert baryonic matter into dark energy as massive stars collapse, growing with the expanding Universe. This fits dark energy data and allows positive neutrino masses, consistent with particle physics.
