Posterior distribution of H₀ and w in flat wCDM cosmology. The black contours show the constraints from TDCOSMO alone, including the TDCOSMO-2025, SLACS, and SL2S lensing datasets. The gray contours show the constraints from Planck. The combination of TDCOSMO with the Planck, DESI BAO, and Pantheon+ is shown with colored contours, as described in the figure legend. The contour levels represent the 1σ and 2σ constraints.
