Revisiting the SN1987A gamma-ray limit on ultralight axion-like particles
Alexandre Payez, Carmelo Evoli, Tobias Fischer +3
We revise the bound from the supernova SN1987A on the coupling of ultralight axion-like particles (ALPs) to photons. In a core-collapse supernova, ALPs would be emitted via the Pri…

Stellar Evolution Bounds on the ALP-Photon Coupling: new Results and Perspectives
Maurizio Giannotti
Stellar evolution considerations are of fundamental importance in our understanding of the axion/ALP-photon coupling, g_{aγ}. Helium burning stars are the best laboratories to stud…

Revisiting the bound on axion-photon coupling from Globular Clusters
Adrian Ayala, Inma Dominguez, Maurizio Giannotti +2
We derive a strong bound on the axion-photon coupling from the analysis of a sample of 39 Galactic Globular Clusters. As recognized long ago, the R parameter, i.e. the num…
