Measuring the Expansion History of the Universe with DESI  

 

Abstract: The DESI survey has just released its second set of results on the expansion history of the Universe. I’ll review the underlying techniques of Baryon Acoustic Oscillations (BAO) in galaxy clustering (plus the Lyα forest), the measurements from DESI, and the challenges these pose to the standard cosmological model. If we have time, I’ll also try to show a demo of how to access the DESI Year 1 data, which is now publicly available, and begin the analysis.
