Cosmological Perturbations of Extreme Axion in the Radiation Era

Ui-Han Zhang, Tzihong Chiueh

Sub-horizon perturbations under the extreme initial condition of the axion model are investigated, where initial axion angles start near the potential maximum. This work focuses on…

Evolution of linear wave dark matter perturbations in the radiation-dominant era

Ui-Han Zhang, Tzihong Chiueh

Linear perturbations of the wave dark matter, or $ψ$ dark matter ( $ψ$ DM), of particle mass $\sim 1 0^{- 22}$ eV in the radiation-dominant era are analyzed, and the matter power spectr…
