The Sun as a target for axion dark matter detection

Published 21 Dec 2023 in hep-ph, astro-ph.HE, and astro-ph.SR | (2312.13984v2)

Abstract: The exploration of the parameter space of axion and axion-like particle dark matter is a major aim of the future program of astroparticle physics investigations. In this context, we present a possible strategy that focuses on detecting radio emissions arising from the conversion of dark matter axions in the Sun's magnetic field, including conversion in sunspots. We demonstrate that near-future low-frequency radio telescopes, such as the SKA Low, may access regions of unexplored parameter space for masses $m_a\lesssim 10{-6}$ eV.

  38. We postpone a full ray-tracing computation to simulate photon propagation in the Sun to future work. Here we accounted for absorption and spatial broadening as described in the text. The bandwidth smearing is instead neglected for simplicity.
