Description

Axions and axion-like particles are well-motivated extensions of the Standard Model and viable dark matter candidates. In the solar interior, these particles can be produced through their couplings to photons, electrons, and nucleons, and can subsequently convert into X-ray photons in the magnetic fields of the solar atmosphere. In this talk, I will present recent searches for such signals using observations of the quiet Sun with the NuSTAR X-ray telescope. These results place competitive constraints on axion couplings to photons, electrons, and nucleons, highlighting solar X-ray observations as a powerful and complementary probe of axion physics.
