Contour levels at the 68.3% (darker) and 95.4% (lighter) CL of H₀ and Ω_m in a flat ΛCDM (fΛCDM) model for different cosmological probes: time-delay cosmography in MACS 1149 (r model; blue), Planck (orange), and BAORSD (red). For completeness, we also show the SH0ES measurement of the Hubble parameter (green; Riess et al. 2021). BAORSD includes Gaussian priors on the values of ω_b and n_s. Details on these datasets are given in Sect. 3.
