Uncovering axion-like particles in supernova gamma-ray spectra
Francesca Calore, Pierluca Carenza, Christopher Eckner +4
A future Galactic Supernova (SN) explosion can lead to a gamma-ray signal induced by ultralight Axion-Like Particles (ALPs) thermally produced in the SN core and converted into hig…
Betelgeuse Constraints on Coupling between Axion-like Particles and Electrons
Mengjiao Xiao, Pierluca Carenza, Maurizio Giannotti +4
Axion-like particles (ALPs) can be produced by thermal processes in a stellar interior, escape from the star and, if sufficiently light, be converted into photons in the external G…
3D template-based -LAT constraints on the diffuse supernova axion-like particle background
Francesca Calore, Pierluca Carenza, Christopher Eckner +7
Axion-like particles (ALPs) may be abundantly produced in core-collapse (CC) supernovae (SNe), hence the cumulative signal from all past SN events can create a diffuse flux peaked…
Constraints on Axion-like Particles from a Hard -ray Observation of Betelgeuse
Mengjiao Xiao, Kerstin M. Perez, Maurizio Giannotti +5
We use the first observation of Betelgeuse in hard -rays to perform a novel search for axion-like particles (ALPs). Betelgeuse is not expected to be a standard source of -ray…
Fermi-LAT and NuSTAR as Stellar Axionscopes
Maurizio Giannotti
We overview the potential of airborne X-ray and gamma-ray telescopes to probe the axion-like particles parameter space.
Impact of Axions on the Minimum Mass of Core Collapse Supernova Progenitors
Inma Dominguez, Maurizio Giannotti, Alessandro Mirizzi +1
In this study we include axions in stellar evolution models adopting the current stringest constraints for their coupling to photons and electrons. We obtain that the minimum stell…
