The passage around this formula
…objects across redshifts from 0.1 to 4.2. Combined with a Big Bang nucleosynthesis prior on the baryon density and the CMB-measured acoustic angular scale, DESI’s first-year analysis returned a matter density of = 0.295 0.015 and = 68.52 0.62 kilometers per second per megaparsec [ 8 ] — a value between the CMB-only and local-ladder numbers, and, notably, mild evidence favoring a dark energy equation of state that evolves with time rather than the constant value assumed by the simplest…
