On the role of injection in kinetic approaches to nonlinear particle acceleration at non relativistic shocks
Stefano Gabici, Pasquale Blasi, Giulia Vannoni
The dynamical reaction of the particles accelerated at a shock front by the first order Fermi process can be determined within kinetic models that account for both the hydrodynamic…
Thermal Particle Injection in Nonlinear Diffusive Shock Acceleration
Donald C. Ellison, Pasquale Blasi, Stefano Gabici
Particle acceleration in collisionless astrophysical shocks, i.e., diffusive shock acceleration (DSA), is the most likely mechanism for producing cosmic rays, at least below 10^{15…
On the role of injection in kinetic approaches to nonlinear particle acceleration at non-relativistic shock waves
P. Blasi, S. Gabici, G. Vannoni
The dynamical reaction of the particles accelerated at a shock front by the first order Fermi process can be determined within kinetic models that account for both the hydrodynamic…
Point-like gamma ray sources as signatures of distant accelerators of ultra high energy cosmic rays
S. Gabici, F. A. Aharonian
We discuss the possibility of observing distant accelerators of ultra high energy cosmic rays in synchrotron gamma rays. Protons propagating away from their acceleration sites prod…
