Generalizes neutrino isocurvature by introducing a mixing angle for the neutrino-matter perturbation ratio and derives first Planck limits on the angle.
Axion stars in miniclusters can reach bosenova conditions within the age of the Universe for QCD axions when initial overdensity exceeds roughly 100, once self-interaction effects are included.

Chiral Gravitational Wave Background from Audible Axion via Nieh-Yan Term
Axion-like fields coupled to the Nieh-Yan term generate a chiral GW background during radiation domination, with parameter space explored for detectability in PTA and space-based observatories.
