Observations from the James Webb Space Telescope (JWST) have unveiled several galaxies with stellar masses $$M_*\gtrsim 10^{10} M_\odot$$ M ∗ ≳ 10 10 M ⊙ at redshifts $$7.4\lesssim z\lesssim 9.1$$ 7.4 ≲ z ≲ 9.1 . These remarkable findings indicate an unexpectedly high stellar mass density, which contradicts the prediction of the $$\Lambda \rm{CDM}$$ Λ CDM model. Our study utilizes the Chevallier–Polarski–Linder (CPL) parameterization, one of the dynamic dark energy models, to probe the role of dark energy on shaping galaxy formation. By considering varying star formation efficiencies within this framework, our analysis demonstrates that in a universe with a higher proportion of dark energy, more massive galaxies are formed at high redshifts, given a fixed perturbation amplitude observed today. These intriguing results highlight the promising prospect of revealing the nature of dark energy by analyzing the high-redshift massive galaxies.

Primordial black holes (PBHs) may have formed through the gravitational collapse of cosmological perturbations that were generated and stretched during the inflationary era, later entering the cosmological horizon during the decelerating phase, if their amplitudes were sufficiently large. In this review paper, we will briefly introduce the basic concept of PBHs and review the formation dynamics through this mechanism, the estimation of the initial spins of PBHs and the time evolution of type II fluctuations, with a focus on the radiation-dominated and (early) matter-dominated phases.
