Axion lines from nuclear de-excitations in galactic stellar populations
Orion Ning, Anupam Ray, Benjamin R. Safdi
We show that mono-energetic axions are produced in abundance through nuclear de-excitations in nearby galaxies such as M87, which is the central galaxy of the Virgo cluster, and th…

Long-lived Axion-Like Particles from Tau Decays
Yohei Ema, Patrick J. Fox, Matheus Hostert +4
Axion-like particles (ALPs) are well-motivated examples of light, weakly coupled particles in theories beyond the Standard Model. In this work, we study long-lived ALPs coupled exc…
