Unveiling Neutrino Nature with the Diffuse Supernova Background
Marco Manno, Pablo Martínez-Miravé, Irene Tamborra
The true nature of neutrinos--whether Dirac or Majorana--is a foundational, unresolved question. We demonstrate that the diffuse supernova neutrino background (DSNB) offers an unta…
Detection horizon for the neutrino burst from the stellar helium flash
Pablo MartÃnez-Miravé, Irene Tamborra, Georg Raffelt
Low-mass stars () ignite helium under degenerate conditions, eventually causing a nuclear run-away -- the helium flash. The alpha-capture process on N…
Matter- and magnetically-driven flavor conversion of neutrinos in magnetorotational collapses
Marco Manno, Pablo MartÃnez-Miravé, Irene Tamborra
The magnetorotational collapse of massive stars copiously emits neutrinos of all flavors, with a prominent hierarchy between the non-electron and electron flavor average energies.…
The Highest-Energy Neutrino Event Constrains Dark Matter-Neutrino Interactions
Toni Bertólez-MartÃnez, Gonzalo Herrera, Pablo MartÃnez-Miravé +1
Dark Matter-neutrino interactions affect the propagation of astrophysical neutrinos, attenuating the flux of neutrinos arriving at Earth. Using the highest-energy neutrino event de…
Neutrinos from stars in the Milky Way
Pablo MartÃnez-Miravé, Irene Tamborra
Neutrinos are produced during stellar evolution by means of thermal and thermonuclear processes. We model the cumulative neutrino flux expected at Earth from all stars in the Milky…
