seen massive breakthroughs in the observations of gamma-ray bursts and other high-energy astrophysical transients. Dynamical jet simulations have progressed to a point where it is now becoming possible to fully numerically resolve gamma-ray burst (GRB) jet
evolution across scales. However, the modeling of radiative emission is currently lagging behind and makes for a bottleneck severely limiting our efforts to fully interpret the physics of GRBs in the multi-messenger era. In this talk, I will present new numerical
developments to resolve this discrepancy and focus on providing insights into GRB afterglow physics. Using numerical simulations, we set out to understand the impact of the presence of multiple emission sites on afterglow light curves. We also investigate
the trans-relativistic evolution of the jet and poorly understood behaviour of the spectral breaks in the radiation as the jet decelerates. In order to do this, we developed a new method for the local numerical calculation of non-thermal emission in relativistic
shocks. This method combines a moving mesh finite-volume code with a local description of particle acceleration and corresponding synchrotron process in a code called GAMMA. The resulting improvements in computational efficiency, and subsequent ability to
reach very high spatial resolution, enables the accurate simulation of GRB afterglow spectral evolution from early to late times. Using these simulations, we can: (i) investigate the short timescale variability of GRB afterglow light curves such as the origin
of flares, (ii) quantify the expected deviations of the approximate analytical methods for the calculation of emissivity that are currently in use in the GRB afterglow community.</span><br class="">
