Abstract: We present the baryon acoustic oscillations results (DR2) from the analysis of the first three years of observations of the DESI instrument corresponding to the Data Release 2 (DR2).

These results represent a significant improvement over the previous BAO analysis released in April 2024, which corresponds to DR1 (one year of observations), as they have a significantly higher statistical volume and a more careful analysis when combining with external datasets such as uncalibrated supernovae and cosmic microwave background data.

These results will be (or have been) publicly released to the arxiv repository this very same morning (the 20th of March).
