"Ï will present two cosmological studies: (1) Extending ΛCDM with dynamical dark energy via Taylor-expanded pressure parametrization; showing First and Second-Order Constraints with Latest Cosmological Data. (2) Gaussian process reconstruction of reionization history from Planck CMB low_l EE data, tightly limiting high-z contributions and exotic injections like decaying dark matter (~1 MeV)."
