Unblinded cosmological constraints from our analysis. Left: final 2D posterior of the time-delay distance D_Δt and the angular diameter distance D_d (emerald contour). The darker and lighter shaded regions in the 2D plots trace 68% and 95% credible regions, respectively. We infer H₀ and Ω_m from this distance posterior accounting for the covariance in a flat ΛCDM cosmology. We take a wide uniform prior on H₀ ∼ 𝒰(0,  150) km s⁻¹ Mpc⁻¹. The blue-shaded region corresponds to a uniform prior Ω_m ∼ 𝒰(0.05,  0.5) and the orange-shaded region corresponds to a Gaussian prior Ω_m ∼ 𝒩(0.334,  0.018) from the Pantheon+ analysis of type Ia supernovae relative distances (Brout et al. 2022). Right: posterior PDF of H₀ and Ω_m in flat ΛCDM cosmology. We constrain H₀ to 9.4% and 9.1% precision for the uniform and Pantheon+ Ω_m-priors, respectively. We show the cosmological parameter posterior from only the 1D D_d posterior with dashed contours with colors matching the associated Ω_m prior. In this case, the H₀ precision is 10.3% and 9.6% for the uniform and Gaussian priors, respectively. The D_d-only constraint on the H₀ is lower by ∼1.4% (0.15σ) than the constraint from the full 2D posterior, for the uniform Ω_m-prior.
