Using GPR-reconstructed angular diameter distances from DESI DR2 BAO and H0LiCOW time-delay lenses, the paper measures γ_PPN = 0.93^{+0.16}_{-0.17} and r_d = 136.36^{+5.14}_{-3.20} Mpc simultaneously without cosmological or gravity assumptions, consistent with GR within 1σ.

Extending to wCDM mainly suppresses the leading Planck Fisher eigenvalue to 2.7% of its LambdaCDM value with only modest eigenmode rotation, while late-time data adds curvature that limits tension relief.
A catalog of 7190 confirmed galaxy clusters from 5-year SPT-3G SZ observations spanning masses 7.9e13 to 1.6e15 solar masses and redshifts 0.037 to >2.
DESI recovers the CMB-constrained parameter combination at sub-percent precision; high-redshift DES supernovae fit flat Lambda CDM while a 0.05 mag offset in the low-redshift anchor sample may be systematic, supporting overall model consistency from recombination to the local universe.
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
The paper reviews standard derivations of light deflection in curved spacetime and presents a unified geometric approach for static and rotating gravitational fields.

Extragalactic test of General Relativity with time-delay gravitational lenses
Using GPR-reconstructed angular diameter distances from DESI DR2 BAO and H0LiCOW time-delay lenses, the paper measures γ_PPN = 0.93^{+0.16}_{-0.17} and r_d = 136.36^{+5.14}_{-3.20} Mpc simultaneously without cosmological or gravity assumptions, consistent with GR within 1σ.

Information-Geometric Perspective on the Hubble Tension: Eigenmode Rotation and Curvature Suppression in wCDM
Extending to wCDM mainly suppresses the leading Planck Fisher eigenvalue to 2.7% of its LambdaCDM value with only modest eigenmode rotation, while late-time data adds curvature that limits tension relief.

Consistency of DES and DESI distances and the Standard Cosmological Model
DESI recovers the CMB-constrained parameter combination at sub-percent precision; high-redshift DES supernovae fit flat Lambda CDM while a 0.05 mag offset in the low-redshift anchor sample may be systematic, supporting overall model consistency from recombination to the local universe.

From Scalar $H_0$ to $E(z)$: A Reformulation of the Hubble Tension
Re-expressing the Hubble tension via posterior-implied E(z) histories yields moderate mismatches (S_hist of 1.65 and 2.55) that correspond to only 1.1-2.1 sigma equivalents, below the usual 4.9 sigma scalar-H0 discrepancy.
