Topic: New analysis of DESI DR2 data jointly tests dark matter and dark energy equation of state assumptions, potentially challenging the standard cosmological model.
Topic: Bayesian selection methods are applied to the interacting dark sector, addressing tensions like the $\sigma_8$ discrepancy between early and late universe observations.
Topic: JWST observations of early reionization are investigated for consistency with CMB data, exploring modified cosmological expansion models.
