The extent of power-law energy spectra in collisionless relativistic magnetic reconnection in pair plasmas
Werner, G.
Using two-dimensional particle-in-cell simulations, we characterize the energy spectra of particles accelerated by relativistic magnetic reconnection (without guide field) in collisionless electron-positron plasmas, for a wide range of upstream magnetizations \sigma and system sizes L. The particle spectra are well-represented by a power law \gamma^{-\alpha}, with a combination of exponential and super-exponential high-energy cutoffs, proportional to \sigma and L, respectively. For large L and \... Show Full Abstract
Using two-dimensional particle-in-cell simulations, we characterize the energy spectra of particles accelerated by relativistic magnetic reconnection (without guide field) in collisionless electron-positron plasmas, for a wide range of upstream magnetizations \sigma and system sizes L. The particle spectra are well-represented by a power law \gamma^{-\alpha}, with a combination of exponential and super-exponential high-energy cutoffs, proportional to \sigma and L, respectively. For large L and \sigma, the power-law index \alpha approaches about 1.2. Show Partial Abstract
