Polarization formalism for ALP-induced X-ray emission from magnetars
Abstract Missions like NASA's Imaging X-ray Polarimetry Explorer (IXPE) are poised to provide an unprecedented view of the Universe in polarized X-rays. Polarization probes physical anisotropies, a fact exploited by particle physicists to look for the anisotropic a E · B operator in the axion-like-particle (ALP) Lagrangian. Such studies have …
