abstract
We show that cold dark matter axions thermalize and form a Bose-Einstein condensate. We obtain the axion state in a homogeneous and isotropic universe, and derive the equations governing small axion perturbations. Because they form a BEC, axions differ from ordinary cold dark matter in the non-linear regime of structure formation and upon entering the horizon. Axion BEC provides a mechanism for the production of net overall rotation in dark matter halos, and for the alignment of cosmic microwave anisotropy multipoles.

Numerical simulations find that black-hole wandering in FDM soliton cores produces intermittent accretion, limiting durable boosts except for ~10^7 solar mass seeds in low-sound-speed gas.
Exact solution of non-minimally coupled massive Klein-Gordon equation in Schwarzschild star metric expressed via general Heun function after geometry-induced coordinate transformation.
Vortex reconnections in BEC/superfluid dark-matter cores can transfer at most 0.06–4.5% of the virial energy in 10 Gyr under fiducial assumptions, so they cannot appreciably restructure the core.
Thesis summarizing an upper limit of 0.12 eV on the neutrino mass sum, bias calibration via CMB lensing cross-correlations, and tighter limits plus stronger normal-ordering preference in non-phantom dynamical dark energy models.
Yukawa screening in the YSP system broadens Bose-star profiles and delays condensation, matching a screened kinetic formula after fitting one normalization parameter.
Review summarizing radio searches for WIMP and ALP dark matter with SKA precursors and forecasts for SKA-Low and SKA-Mid telescopes.
