Shock precursor type changes ion and electron acceleration
Simulations reveal two distinct regimes in transrelativistic shocks where competing plasma instabilities produce dramatically different particle acceleration efficiencies for ions and electrons.

Approximate shock models fail at sufficiently high velocities
Numerical model reveals that simplified approximations for synchrotron emission from relativistic shocks can be inaccurate by over an order of magnitude, biasing inferred properties of transients.
