Reconciling hints on axion-like-particles from high-energy gamma rays with stellar bounds
Gautham Adamane Pallathadka, Francesca Calore, Pierluca Carenza +9
It has been recently claimed by two different groups that the spectral modulation observed in gamma rays from Galactic pulsars and supernova remnants can be due to conversion of ph…
Gamma-ray spectral modulations of Galactic pulsars caused by photon-ALPs mixing
Jhilik Majumdar, Francesca Calore, Dieter Horns
Well-motivated extensions of the standard model predict ultra-light and fundamental pseudo-scalar particles (e.g., axions or axion-like particles: ALPs). Similarly to the Primakoff…
Spectral modulation of non-Galactic plane Gamma-ray pulsars due to photon-ALPs mixing in Galactic magnetic field
Jhilik Majumdar, Francesca Calore, Dieter Horns
In many approaches to describe physics beyond the standard model, light Nambu-Goldstone bosons (named axion-like particles or ALPS for their similarity with the axion) are predicte…
