Title: Radiation mediated shocks in gamma-ray bursts</div>

Abstract: The roles of radiation mediated shocks (RMSs) and shock breakouts in the prompt emission of gamma-ray bursts (GRBs) have been studied for twenty years. However, so far, no such model has been fit to data due to their computational complexity. We aim
to bridge this gap between theory and observation. In this talk, I will present an analogy that we have developed for this purpose, which is based on the similar evolution of the photon spectrum in an RMS and in repeated Compton scatterings with high-energy,
thermal electrons. With this analogy we can accurately replicate spectra generated by a full-scale RMS simulation using a fraction of the computing time, allowing us to probe a large enough parameter space to fit the model to data. Finally, I will present
fits to the prompt emission of the archetypical photospheric burst GRB 090902B. </div>
