Corner plot obtained by superimposing the ΛCDM, oΛCDM, wCDM, owCDM, CPL, logarithmic, exponential, JBP, BA, and GEDE models using DESI DR2 Lyα forest measurements in combination with the CMB, galaxy BAO, and SN Ia (Pantheon+, DES-Dovekie, and Union3) datasets. The contours correspond to the 68% (1σ) and 95% (2σ) confidence levels. The cross symbols indicate parameters that are not present in the corresponding models.
