Testing Exponential f(R) Gravity with CMB, DESI-DR2, and Supernova Data
Exponential f(R) gravity tested on combined CMB, DESI-DR2 and supernova data yields higher S8 and slightly lower H0 than LambdaCDM, alleviating S8 tension by up to 1.2 sigma but not H0 tension.

What it takes to solve the Hubble tension through Modifications of Cosmological Recombination II: in light of ACT DR6 and DESI DR2
Perturbative modifications to the electron mass m_e(z) resolve the Hubble tension with Planck+ACT CMB data but cannot when DESI DR2 BAO data are added due to lowered Omega_m.

A Review on Resolving the Hubble Tension via Late-Universe Physics
A review of late-universe models concludes that DESI BAO plus uncalibrated supernovae data indicate the Hubble tension originates in new low-redshift physics.

Alleviating the Hubble tension with the Λ_(ω_s)CDM model
Λ_{ω_s}CDM adds a subdominant early barotropic fluid with fitted ω_s ≈ 0.294 and Ω_s ≈ 1.62×10^{-5}, producing H0 = 71.51 km/s/Mpc from MCMC fits to Planck 2018, DESI DR2, and Pantheon+SH0ES data.

Resolving the Hubble Tension in the Early Dark Energy Framework with JWST and DESI Data
Axion EDE model fitted to Planck/ACT/SPT CMB, DESI BAO, and JWST UV luminosity function data yields H0 = 71.58 ± 1.05 km s^{-1} Mpc^{-1}, reduces H0 tension to 1.0 sigma, and improves Δχ^{2}_tot = -18.26 over Λ CDM.

Interplay of Holographic and New Agegraphic Dark Energy in Cosmology: A hybrid dark energy model from a generalized length-time cut-off
A hybrid holographic-new agegraphic dark energy model is built from a combined length-time cutoff, studied in interacting and non-interacting cases with cold dark matter, and constrained using Hubble, BAO, and DESI data.

Probing dynamical dark energy with late-time data: Evidence, tensions, and the limits of the w₀w_aCDM framework
Evidence for dynamical dark energy in the w0waCDM framework is strongly dataset-dependent, driven by mismatches in low-redshift BAO distance ratios that produce divergent expansion histories and inconsistent Hubble tension relief.
