Updated constraints on axion-like particles from temporal information in supernova SN1987A gamma-ray data
Sebastian Hoof, Lena Schulz
We revise gamma-ray limits on axion-like particles (ALPs) emitted from supernova SN1987A based on Solar Maximum Mission data. We improve and simplify the computation of the expecte…

Cosmological constraints on decaying axion-like particles: a global analysis
Csaba Balázs, Sanjay Bloor, Tomás E. Gonzalo +8
Axion-like particles (ALPs) decaying into photons are known to affect a wide range of astrophysical and cosmological observables. In this study we focus on ALPs with masses in the…
