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…
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…
Heavy axion-like particles and core-collapse supernovae: constraints and impact on the explosion mechanism
Giuseppe Lucente, Pierluca Carenza, Tobias Fischer +2
Heavy axion-like particles (ALPs), with masses keV, coupled with photons, would be copiously produced in a supernova (SN) core via Primakoff process and photon co…
Constraints on the coupling with photons of heavy axion-like-particles from Globular Clusters
Pierluca Carenza, Oscar Straniero, Babette Döbrich +3
We update the globular cluster bound on massive ( up to a few 100 keV) axion-like particles (ALP) interacting with photons. The production of such particles in the stellar cor…
