![A graph of the evolution of the dark energy (vertical axis) as a function of time (redshift on the horizontal axis) - showing an offset from the cosmological constant (a flat horizontal line). Here is the figure caption from the paper:
FIG. 12. Comparison of the constraints on the equation of
state of dark energy using the CPL parametrization and a bin-
ning reconstruction approach, using DESI+CMB+DESY5.
The solid green line shows the best-fit w(z) based on w0 and
wa inference and the green contours around it represent the
68% and 95% confidence intervals. We also show in blue the
constraints from the binning approach [47], with the hori-
zontal bars indicating the bin width (which is fixed) and the
vertical bars representing the 1σ error. Additionally, we in-
clude in gray the 1D posterior for each binning parameter.
The ΛCDM limit corresponds to the horizontal gray dashed
line.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ok3ms3dzop7gcwejp7lswhpi/bafkreiaa64kyfu7u5ber7u6kwk2zzkuet66j6o3l4lr5ftl5sef67pzham)
