This page presents a few applications of the Zeltron code to astrophysical problems.
2D relativistic reconnection simulation
Electron-positron plasma density of a 2D simulation of relativistic reconnection with synchrotron radiation reaction force. White contours show the magnetic field lines. This simulation was performed to explain flashes of energetic gamma rays from the Crab Nebula (see Cerutti et al. 2013).
3D relativistic reconnection simulation
Same as above but in 3D (see Cerutti et al. 2014). The isosurfaces show the plasma density.
2D axisymmetric pulsar simulation
Trajectories of electrons created at the surface of a neutron star, whose magnetic axis is aligned with its rotation axis. In this simulations, a few electrons are accelerated to high energies in the equatorial regions where magnetic field lines reconnect. The black solid lines show the poloidal magnetic field lines (see Cerutti et al. 2015).
3D pulsar simulation
High-energy radiation flux emitted in the vicinity of a pulsar (black sphere) whose magnetic axis (red arrow) is inclined by 30° with respect to the rotation axis (blue arrow). Black lines represent the last closed and first open magnetic field lines. These simulations were performed to uncover the precise location of particle acceleration and gamma-ray emission in pulsars (see Cerutti et al. 2015).
