A New Time-Dependent Finite Difference Method for Relativistic Shock Acceleration
Sean Delaney, Paul Dempsey, Peter Duffy +1
We present a new approach to calculate the particle distribution function about relativistic shocks including synchrotron losses using the method of lines with an explicit finite d…
Relativistic Shock Acceleration: A Hartree-Fock Approach
Paul Dempsey, John G. Kirk
We examine the problem of particle acceleration at a relativistic shocks assuming pitch-angle scattering and using a Hartree-Fock method to approximate the associated eigenfunction…
Particle acceleration by multiple parallel shocks
Joni Tammi, Paul Dempsey
We present both numerical and semi-analytical results on test-particle acceleration in multiple parallel shocks. We apply a kinetic Monte Carlo code and an eigenfunction expansion…
Radiative losses and cut-offs of energetic particles at relativistic shocks
Paul Dempsey, Peter Duffy
We investigate the acceleration and simultaneous radiative losses of electrons in the vicinity of relativistic shocks. Particles undergo pitch angle diffusion, gaining energy as th…
Particle Acceleration at Multiple Internal Relativistic Shocks
Paul Dempsey, Peter Duffy
Relativistic shocks provide an efficient method for high-energy particle acceleration in many astrophysical sources. Multiple shock systems are even more effective and of importanc…
