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…
Testing extended theories of gravity with GRBs
L. Mastrototaro, G. Lambiase
We present our studies on the neutrino pairs annihilation into electron-positron pairs () near the surface of a neutron star in the framework of extended theor…
Neutrino spin oscillations in conformally gravity coupling models and quintessence surrounding a black hole
Leonardo Mastrototaro, Gaetano Lambiase
In this paper, we study the spin transitions of neutrinos caused by the interaction with a gravitational field. We consider a model with a scalar field (describing screening effect…
Massive sterile neutrinos in the early universe: From thermal decoupling to cosmological constraints
Leonardo Mastrototaro, Pasquale Dario Serpico, Alessandro Mirizzi +1
We consider relatively heavy neutrinos , mostly contributing to a sterile state , with mass in the range 10 MeV MeV, which are therma…
