511 keV line constraints on feebly interacting particles from supernovae
Francesca Calore, Pierluca Carenza, Maurizio Giannotti +4
Feebly interacting particles with masses with O(10-100) MeV can be copiously produced by core-collapse supernovae (SNe). In this paper we consider the case of MeV-ish sterile neutr…
Supernova bounds on axion-like particles coupled with nucleons and electrons
Francesca Calore, Pierluca Carenza, Maurizio Giannotti +3
We investigate the potential of type II supernovae (SNe) to constrain axion-like particles (ALPs) coupled simultaneously to nucleons and electrons. ALPs coupled to nucleons can be…
Supernova bound on Axion-Like Particles coupled with electrons
Giuseppe Lucente, Pierluca Carenza
Axion-Like Particles (ALPs) coupled with electrons would be produced in a Supernova (SN) via electron-proton bremsstrahlung and electron-positron fusion. We evaluate the ALP emissi…
Axion-like Particles from Hypernovae
Andrea Caputo, Pierluca Carenza, Giuseppe Lucente +5
It was recently pointed out that very energetic subclasses of supernovae (SNe), like hypernovae and superluminous SNe, might host ultra-strong magnetic fields in their core. Such f…
Revisiting axion-electron bremsstrahlung emission rates in astrophysical environments
Pierluca Carenza, Giuseppe Lucente
The axion-electron coupling is a generic feature of non-hadronic axion models. This coupling may induce a variety of observable signatures, particularly in astrophysical e…
