Axions are candidates for dark matter in the universe.We develop an accurate Boltzmann code to calculate the linear growth of the plasma. As an interesting example, we investigate a mixed dark matter model consisting of cold dark matter (CDM) and two-axion dark matter. We analyze the growth of the structure numerically and analytically. We find that an effective single axion with an effective mass and an effective abundance is useful to characterize the two-axion cosmology. Moreover, we generalize the effective single axion description to multi-axion dark matter cosmology. We also compare the results with those of warm dark matter (WDM) model. Moreover, we calculate halo mass functions for the mixed model by using the Press-Schechter model and linear perturbations and then determine the mass function as a function of masses and axion abundance.

Fuzzy Axions and Associated Relics
In explicit string theory compactifications, fuzzy axion dark matter is rare and typically requires fine-tuning of initial axion displacements or a non-standard reheating epoch to avoid overproducing heavier axions.

Accurate method for ultralight axion CMB and matter power spectra
AxiECAMB computes CMB and matter power spectra for ultralight axions across 10^-33 to 10^-18 eV by time-averaging fast field oscillations, with metric and fluid matching that reduces errors far below cosmic variance f...

Supermassive Binaries in Ultralight Dark Matter Solitons
High-resolution simulations show that a symmetric SMBH binary decays faster in a ULDM soliton than semi-analytic estimates predict, due to soliton pinching, with implications for the final parsec problem and PTA gravi...
