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…
Fast X-ray Variability from the Coronae of Supermassive Black Holes
Xiurui Zhao, Luca Comisso, Stefano Marchesi +4
We present the first systematic study of short-timescale X-ray variability in radio-quiet active galactic nuclei (AGN), utilizing archival Chandra observations of approximately 3,0…
Magnetic Field-Line Curvature and Its Role in Particle Acceleration by Magnetically Dominated Turbulence
Samuel Sebastian, Luca Comisso
We employ first-principles, fully kinetic particle-in-cell simulations to investigate magnetic field-line curvature in magnetically dominated turbulent plasmas and its role in part…
Intermittency in Collisionless Large-Amplitude Turbulence
Ryan Golant, Luca Comisso, Philipp Kempski +1
Large-amplitude turbulence -- characterized by a fluctuating magnetic field component, , that is stronger than the mean component, -- is generically intermittent, populat…
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…
Ultra-High-Energy Cosmic Rays Accelerated by Magnetically Dominated Turbulence
Luca Comisso, Glennys R. Farrar, Marco S. Muzio
Ultra-High-Energy Cosmic Rays (UHECRs), particles characterized by energies exceeding eV, are generally believed to be accelerated electromagnetically in high-energy astr…
