High-intensity lasers are becoming a new source of high-energy particles and radiation, and can probe fundamental questions about particle dynamics in strong fields. The challenge is reliably predicting the energy and distribution of emitted photons in experiments, because both classical and quantum particle dynamics are important and involve physics at many length scales. I will introduce general phenomenology and order-of-magnitude expectations from numerical plasma simulation. I will then explain factorization of the photon angular distribution as a general and systematic framework to separate classical plasma dynamics from high-energy photon emission and better utilize simulations for predictions.
