Anisotropy-driven constraints on the transition from Galactic to extragalactic cosmic-ray sources
Teresa Bister, Foteini Oikonomou, Damiano F. G. Fiorillo
The spatial distribution of the cosmic-ray (CR) flux above exhibits a significant dipole in agreement with expectations from extragalactic sources following the l…
Neutrinos and gamma rays from Seyfert galaxies constrain the properties of coronal turbulence
Federico Testagrossa, Damiano F. G. Fiorillo, Luca Comisso +3
The TeV neutrino signal observed by IceCube from the active galactic nucleus (AGN) NGC 1068 can probe its innermost coronal regions. If these neutrinos originate from hadrons accel…
Single-source-class interpretation of the diffuse astrophysical neutrino flux
Walter Winter, Damiano F. G. Fiorillo, Sara Buson
We explore the interpretation that the diffuse astrophysical neutrino flux is dominated by a single standard candle-like source class. Since recent observations favor a broken powe…
Diffuse neutrino flux from coronal magnetospheric current sheets of accreting black holes
Despina Karavola, Maria Petropoulou, Damiano F. G. Fiorillo +2
Non-jetted AGN exhibit hard X-ray emission with a power law spectrum above 2 keV, which is thought to be produced through Comptonization of soft photons by electrons and posi…
Neutrinos from core-collapse supernovae
Georg G. Raffelt, Hans-Thomas Janka, Damiano F. G. Fiorillo
The core of a massive star (M > 8 Msun) eventually collapses. This implosion usually triggers a supernova (SN) explosion that ejects most of the stellar envelope and leaves behind…
A generalized study of linear electromagnetic cascades in astrophysical sources
Damiano F. G. Fiorillo, Federico Testagrossa, Chengchao Yuan +2
High-energy gamma rays can trigger electromagnetic cascades via pair production on ambient photons, reprocessing their energy to lower frequencies. A classic example is the cascade…
Coupled Time-Dependent Proton Acceleration and Leptonic-Hadronic Radiation in Turbulent Supermassive Black Hole Coronae
Chengchao Yuan, Damiano F. G. Fiorillo, Maria Petropoulou +1
Turbulent coronae of supermassive black holes can accelerate non-thermal particles to high energies and produce observable radiation, but capturing this process is challenging due…
The contribution of turbulent AGN coronae to the diffuse neutrino flux
Damiano F. G. Fiorillo, Luca Comisso, Enrico Peretti +2
Active galactic nuclei (AGN) can accelerate protons to energies of 10-100 TeV, with secondary production of high-energy neutrinos. If the acceleration is driven by magnetized…
Can the neutrinos from TXS 0506+056 have a coronal origin?
Damiano F. G. Fiorillo, Federico Testagrossa, Maria Petropoulou +1
The blazar TXS 0506+056 has been the first astrophysical source associated with high-energy astrophysical neutrinos, and it has emerged as the second-most-prominent hotspot in the…
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…
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…
Identifying Energy-Dependent Flavor Transitions in High-Energy Astrophysical Neutrino Measurements
Qinrui Liu, Damiano F. G. Fiorillo, Carlos A. Argüelles +3
The flavor composition of TeV--PeV astrophysical neutrinos, i.e., the proportion of neutrinos of different flavors in their flux, is a versatile probe of high-energy astrophysics a…
TeV neutrinos and hard X-rays from relativistic reconnection in the corona of NGC 1068
Damiano F. G. Fiorillo, Maria Petropoulou, Luca Comisso +2
The recent discovery of astrophysical neutrinos from the Seyfert galaxy NGC 1068 suggests the presence of non-thermal protons within a compact "coronal" region close to the central…
