Neutrino flavor conversion alters the lepton-emission self-sustained asymmetry in core-collapse supernovae
Noah Roux, Irene Tamborra, Maryna Mesiura
We solve the neutrino equations of motion in a half annulus, accounting for two spatial dimensions. At any location in the annulus, the neutrino momentum is characterized by a pola…
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…
Interacting Supernovae: a Radio and X-ray Strategy to Constrain the Structure of the Circumstellar Medium
Shunke Ai, Irene Tamborra, Leonardo Dinoi
The interaction of supernova (SN) ejecta with the dense circumstellar medium (CSM) converts shock kinetic energy into radiation across multiple wavebands. We investigate the depend…
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…
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…
Neutrino Flavor Conversion Shapes the Rate of Failed Core-collapse Supernovae
Mariam Gogilashvili, Irene Tamborra
The relative rate of neutron stars and black holes produced by the collapse of massive stars is highly uncertain. We simulate the stellar collapse of progenitors with masses…
Matter- and magnetically-driven flavor conversion of neutrinos in magnetorotational collapses
Marco Manno, Pablo Martínez-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.…
Detection horizon for the neutrino burst from the stellar helium flash
Pablo Martínez-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…
Magnetized Shocks Mediated by Radiation from Leptonic and Hadronic Processes
Shunke Ai, Irene Tamborra
Shocks in astrophysical transients are key sites of particle acceleration. If the shock upstream is optically thick, radiation smoothens the velocity discontinuity at the shock (ra…
Steady state of fast-oscillating neutrinos in an inhomogeneous medium
Manuel Goimil-García, Irene Tamborra
The streaming of neutrinos in an inhomogeneous medium is known to affect the physics of flavor conversion. We employ an ensemble of single-crossed angular distributions and explore…
Neutrinos from stars in the Milky Way
Pablo Martínez-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…
Collapsar Disk Outflows III: Detectable Neutrino and Gravitational Wave Signatures
Rodrigo Fernández, Silas Janke, Coleman Dean +1
We investigate the neutrino and gravitational wave (GW) signals from accretion disks formed during the failed collapse of a rotating massive star (a collapsar). Following black hol…
Electron-neutrino lepton number crossings: Variations with the supernova core physics

Marie Cornelius, Irene Tamborra, Malte Heinlein +1
Fast neutrino flavor conversion may impact the explosion mechanism and nucleosynthesis in core-collapse supernovae. A necessary condition for fast flavor conversion is the presence…
