Acceleration time scale in an ultrarelativistic shock
نویسنده
چکیده
The acceleration mechanism at ultrarelativistic shocks is investigated using the Monte Carlo simulations. We apply a method of discrete small amplitude particle momentum scattering to reproduce highly anisotropic conditions at the shock and carefully describe the acceleration mechanism. The obtained acceleration times equal 1.0 rg/c if the spectral index reach the value of 2.2, independent of physical conditions in the shock. Some other parameters of the acceleration process are also provided.

Simulation Studies of Electron Acceleration to Ultrarerativistic Energies Caused by Small Pulses Generated in Shock Waves
Electron acceleration caused by small pulses in shock waves is studied with relativistic particle simulations. The simulations show that a compressive small pulse generated in a shock wave can accelerate electrons to ultrarelativistic energies. If the external magnetic field is reversed across a neutral sheet, the shock wave creates a field-reversed small pulse, in addition to compressive ones,...
متن کاملShock Vorticity Generation from Accelerated Ion Streaming in the Precursor of Ultrarelativistic Gamma-ray Burst External Shocks
We investigate the interaction of nonthermal ions (protons and nuclei) accelerated in an ultrarelativistic blastwave with the pre-existing magnetic field of the medium into which the blastwave propagates. While particle acceleration processes such as diffusive shock acceleration can accelerate ions and electrons, the accelerated electrons suffer larger radiative losses. Under certain conditions...
متن کاملCosmic rays acceleration at ultrarelativistic subshocks
We present the model of cosmic rays acceleration at ultrarelativistic subshocks and confront it with the observations of gamma-ray bursts (GRBs) and blazars. We investigate cosmic rays acceleration in shocks with Lorentz factors (γ) in the range 3 40. We show that fluctuations of the magnetic field downstream of the shock do not play an important role in the acceleration process. Results of num...
متن کاملAcceleration time scale at ultrarelativistic shock waves
The first-order cosmic ray acceleration at ultrarelativistic shocks is investigated using the Monte Carlo method. We apply a method of discrete particle momentum scattering as a model of particle pitch angle diffusion to reproduce highly anisotropic conditions at the shock wave. Shocks with Lorentz factors γ up to 320 and varying magnetic field inclinations ψ are considered. Values of diffusion...
متن کاملElectron Acceleration at Pulsar Wind Termination Shocks
We study the acceleration of electrons and positrons at an electromagnetically modified, ultrarelativistic shock in the context of pulsar wind nebulae (PWNe). We simulate the outflow produced by an obliquely rotating pulsar in proximity of its termination shock with a two-fluid code which uses a magnetic shear wave to mimic the properties of the wind. We integrate electron trajectories in the t...
