Updated observational constraints on spatially-flat and non-flat $\Lambda$CDM and XCDM cosmological models

Understand

We study 6 LCDM models, with 4 allowing for non-flat geometry and 3 allowing for a non-unity lensing consistency parameter $A_L$.

• We also study 6 XCDM models with a dynamical dark energy density X-fluid with equation of state $w$.
• For the non-flat models we use two different primordial power spectra, Planck $P(q)$ and new $P(q)$.
• These models are tested against: Planck 2018 CMB power spectra (P18) and lensing potential power spectrum (lensing), and an updated compilation of BAO, SNIa, $H(z)$, and $f\sigma_8$ data [non-CMB data].
