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…
Revisiting magnon bound states: ferro-antiferromagnetic square-lattice model
Cesar A. Gallegos, A. L. Chernyshev
A comprehensive analysis of pairing and bound states of magnons in the Heisenberg square-lattice ferro-antiferromagnetic model is presented. We highlight…
Quasi-steady flavor configuration of multi-energy neutrino ensembles
Manuel Goimil-García, Irene Tamborra
Neutrino flavor conversion profoundly impacts the explosion mechanism and multi-messenger emissions of core-collapse supernovae. Yet, state-of-the-art hydrodynamic simulations of n…
Diffuse Neutrino Background from Magnetorotational Stellar Core Collapses
Pablo MartÃnez-Miravé, Irene Tamborra, Miguel Ãngel Aloy +1
A statistically significant detection of the diffuse supernova neutrino background (DSNB) is around the corner. To this purpose, we assess the contribution to the DSNB of magnetoro…
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…
Flavor Conversion Enhances or Suppresses Supernova Explodability Independent of the Progenitor Mass
Mariam Gogilashvili, Irene Tamborra
Flavor conversion can affect the neutrino-driven delayed explosion mechanism of collapsing massive stars, altering the efficiency of shock revival. We perform core-collapse superno…
