Intermittency and Dissipative Structures Arising from Relativistic Magnetized Turbulence
Zachary Davis, Luca Comisso, Dimitrios Giannios
Kinetic simulations of relativistic turbulence have significantly advanced our understanding of turbulent particle acceleration. Recent progress has highlighted the need for an upd…
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…
Pitch-Angle Anisotropy Imprinted by Relativistic Magnetic Reconnection
Luca Comisso, Brian Jiang
Radiation emitted by nonthermal particles accelerated during relativistic magnetic reconnection is critical for understanding the nonthermal emission in a variety of astrophysical…
Generation of near-equipartition magnetic fields in turbulent collisionless plasmas
L. Sironi, L. Comisso, R. Golant
The mechanisms that generate "seed" magnetic fields in our Universe and that amplify them throughout cosmic time remain poorly understood. By means of fully-kinetic particle-in-cel…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
Ultrafast Variability in AGN Jets: Intermittency and Lighthouse Effect
Emanuele Sobacchi, Tsvi Piran, Luca Comisso
Gamma-ray flares from Active Galactic Nuclei (AGN) show substantial variability on ultrafast timescales (i.e. shorter than the light crossing time of the AGN's supermassive black h…
