Evolution of perturbation and power spectrum in a two-component ultralight axionic universe

چکیده
The evolution of cosmic perturbations in a two-component ultralight axionic universe is investigated. We present the first spectral computation multi-component universes. A particular case composed light extreme axions and free massive particles offers possibility for formation very high-redshift galaxies, which are typically required to host early quasars. Our retains information perturbed velocities individual axion components, opening new avenue setting up initial conditions future dark matter simulations.

15 صفحه اولThird Order Density Perturbation and One-loop Power Spectrum in a Dark Energy Dominated Universe
We investigate the third-order density perturbation and the one-loop correction to the linear power spectrum in the dark energy cosmological model. Our main interest is to understand the dark energy effect on the baryon acoustic oscillation in quasi-nonlinear regime (k ≈ 0.1h/Mpc). Analytical solutions and simple fitting formulae are presented for the dark energy model with the general time var...
