SU(2)_F bosons in a U(2)_F flavor model induce unsuppressed flavor-violating couplings, with K to pi X and mu to e X constraining the breaking scale v_phi to 10^11-10^12 GeV for light bosons and other processes constraining heavier states.

Stripped-envelope supernovae enable QCD axion detection to masses around 10^{-4} eV via gamma-ray signals from conversion in progenitor magnetic fields.
Turbulent magnetic fields enhance axion-photon conversion signals from supernovae, improving limits on axion-proton and axion-photon couplings by up to two orders of magnitude.
The study calculates sensitivity of space- and Moon-based radio telescopes to resonant light dark matter conversion in solar system targets, finding encouraging prospects for dark photon searches with the Sun and axion-like particle conversion in Jupiter's magnetosphere.
