Probing Heavy Axion-like Particles from Massive Stars with X-rays and Gamma Rays
James H. Buckley, P. S. Bhupal Dev, Francesc Ferrer +1
The hot interiors of massive stars in the later stages of their evolution provide an ideal place for the production of heavy axion-like particles (ALPs) with mass up to O(100 keV)…
