The RadioAxion experiment at Gran Sasso found no evidence for axion dark matter induced periodic modulations in 241Am decays and derived constraints on the axion decay constant for masses from 10^{-21} to 10^{-9} eV.

Collective nucleon scattering in neutron-star matter suppresses the effective absorption of ultralight bosons at the long wavelengths relevant for superradiance, weakening the link between stellar cooling bounds and superradiant instability rates.
A framework is developed to predict axion-induced time modulations in weak nuclear decays, used to derive constraints on the axion decay constant from reanalyzed Gran Sasso data on 40K and 137Cs and to propose future sensitivity to higher masses.
