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.

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.

Black Holes that Convert Matter into Dark Energy Allow for Positive Neutrino Masses

DESI Survey @desisurvey.bsky.social · Aug 22

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.

🕳️✨ What if black holes don’t just swallow matter… but transform it into dark energy?

🔊 New BAO analysis from the 3-year observations (DR2). Long story short, as follows.
1. DESI alone is consistent with LCDM. 👉 Boring
2. DESI and Planck have a 2.3 discrepancy in Ωm-H0rd plane. 👉Interesting.

This is starting to look believable (to me at least 😅)

*Something* is certainly going on...

Great work @desisurvey.bsky.social!
