Abstract

We discuss the diversity of prompt Gamma-Ray Burst (GRB) spectra from high to low energies, comparing optical observations to simultaneous gamma-ray emission. These events show a wide variety of relations between γ-ray and optical spectral and temporal properties. Using optical detections and limits from ROTSE as well as the literature, we constrain the broad-band spectral shape during GRB events. With no single result for low-energy emission behavior, GRB models will need to account for diverse outcomes. © Società Italiana di Fisica
