Fast Flavor Pendulum: Instability Condition
Damiano F. G. Fiorillo, Manuel Goimil-García, Georg G. Raffelt
Even in the absence of neutrino masses, a neutrino gas can exhibit a homogeneous flavor instability that leads to a periodic motion known as the fast flavor pendulum. A well-known…
NuSTAR bounds on radiatively decaying particles from M82
Francisco R. Candón, Damiano F. G. Fiorillo, Giuseppe Lucente +2
Axions and other putative feebly interacting particles (FIPs) with a mass of tens to several hundreds of keVs can be produced in stellar cores with a Lorentz boost factor $E_a/m_a\…
Theory of neutrino slow flavor evolution. Part I. Homogeneous medium
Damiano F. G. Fiorillo, Georg G. Raffelt
Dense neutrino gases can exhibit collective flavor instabilities, triggering large flavor conversions that are driven primarily by neutrino-neutrino refraction. One broadly disting…
Theory of neutrino fast flavor evolution. Part II. Solutions at the edge of instability
Damiano F. G. Fiorillo, Georg G. Raffelt
In dense neutrino environments, such as provided by core-collapse supernovae or neutron-star mergers, neutrino angular distributions may be unstable to collective flavor conversion…
A magnetized strongly turbulent corona as the source of neutrinos from NGC 1068
Damiano F. G. Fiorillo, Luca Comisso, Enrico Peretti +2
The cores of active galactic nuclei (AGN) are potential accelerators of 10-100 TeV cosmic rays, in turn producing high-energy neutrinos. This picture was confirmed by the compellin…
The next galactic supernova can uncover mass and couplings of particles decaying to neutrinos
Bernanda Telalovic, Damiano F. G. Fiorillo, Pablo Martínez-Miravé +2
Many particles predicted by extensions of the Standard Model feature interactions with neutrinos, e.g., Majoron-like bosons . If the mass of is larger than about 10 keV, the…
Neutrino emission in cold neutron stars: Bremsstrahlung and modified urca rates reexamined
Salvatore Bottaro, Andrea Caputo, Damiano Fiorillo
Neutrino emission in cold neutron stars is dominated by the modified urca (murca) process and nucleon-nucleon bremsstrahlung. The standard emission rates were provided by Friman an…
Theory of neutrino fast flavor evolution. Part I. Linear response theory and stability conditions
Damiano F. G. Fiorillo, Georg G. Raffelt
Neutrino-neutrino refraction leads to collective flavor evolution that can include fast flavor conversion, an ingredient still missing in numerical simulations of core-collapse sup…
New limits on neutrino decay from high-energy astrophysical neutrinos
Victor B. Valera, Damiano F. G. Fiorillo, Ivan Esteban +1
Since neutrinos have mass differences, they could decay into one another. But their lifetimes are likely long, even when shortened by new physics, so decay likely impacts neutrinos…
Self-Interacting Dark Sectors in Supernovae Can Behave as a Relativistic Fluid
Damiano F. G. Fiorillo, Edoardo Vitagliano
We revisit supernova (SN) bounds on a hidden sector consisting of millicharged particles and a massless dark photon. Unless the self-coupling is fine-tuned to be small, rather…
Fast flavor conversions at the edge of instability in a two-beam model
Damiano F. G. Fiorillo, Georg Raffelt
A dense neutrino gas exhibiting angular crossings in the electron lepton number is unstable and develops fast flavor conversions. Instead of assuming an unstable configuration from…
Collective neutrino-antineutrino oscillations in dense neutrino environments?
Damiano F. G. Fiorillo, Georg G. Raffelt, Günter Sigl
The paradigm-changing possibility of collective neutrino-antineutrino oscillations was recently advanced in analogy to collective flavor oscillations. However, the amplitude for th…
Inhomogeneous Kinetic Equation for Mixed Neutrinos: Tracing the Missing Energy
Damiano F. G. Fiorillo, Georg G. Raffelt, Günter Sigl
Flavor-dependent neutrino transport is described by a well-known kinetic equation for occupation-number matrices in flavor space. However, as an overlooked theoretical problem, we…
