Bulk Motions in the Black Hole Jet Sheath as a Candidate for the Comptonizing Corona
Navin Sridhar, Bart Ripperda, Lorenzo Sironi +2
Using two-dimensional general relativistic resistive magnetohydrodynamic simulations, we investigate the properties of the sheath separating the black hole jet from the surrounding…
Electrostatic Waves and Electron Holes in Simulations of Low-Mach Quasi-Perpendicular Shocks
Artem Bohdan, Aaron Tran, Lorenzo Sironi +1
Collisionless low Mach number shocks are abundant in astrophysical and space plasma environments, exhibiting complex wave activity and wave-particle interactions. In this paper, we…
Particle Acceleration and Nonthermal Emission at the Intrabinary Shock of Spider Pulsars. I: Non-Radiative Simulations
Jorge Cortés, Lorenzo Sironi
Spider pulsars are compact binary systems composed of a millisecond pulsar and a low-mass companion. Their X-ray emission - modulated on the orbital period - is interpreted as sync…
Long-term Evolution of Relativistic Unmagnetized Collisionless Shocks
Daniel Groselj, Lorenzo Sironi, Anatoly Spitkovsky
We study a relativistic collisionless electron-positron shock propagating into an unmagnetized ambient medium using 2D particle-in-cell simulations of unprecedented duration and si…
Synchrotron polarization signatures of surface waves in supermassive black hole jets
Jordy Davelaar, Bart Ripperda, Lorenzo Sironi +7
Supermassive black holes in active galactic nuclei (AGN) are known to launch relativistic jets, which are observed across the entire electromagnetic spectrum and are thought to be…
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…
