Cosmological constraints on heavy sterile neutrinos
L. Mastrototaro
We consider heavy sterile neutrinos , with mass in the range 10 MeV MeV, thermally produced in the early universe and freezing out after t…
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…
Neutrino pair annihilation () in the presence of quintessence surrounding a black hole
G. Lambiase, L. Mastrototaro
Quintessence fields, introduced to explain the speed-up of the Universe, might affect the geometry of spacetime surrounding black holes, as compared to the standard Schwarzschild a…
Einstein, Planck and Vera Rubin: relevant encounters between the Cosmological and the Quantum Worlds
Paolo Salucci, Giampiero Esposito, Gaetano Lambiase +38
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?, th…
