Resumen:

Photospheric emission is an unavoidable component of the prompt emission of gamma-ray bursts. Its magnitude and spectral shape are, however, uncertain and depend on jet properties such as its magnetization and the dissipation mechanism and location. Some models call for a dominant role of photospheric emission in the prompt spectrum, while others only contain a small photospheric contribution. We present a review of numerical results on the properties of the photospheric emission in long-duration gamma-ray bursts, discussing the role of the photospheric component in the explanation of ensemble correlations and the origin of its non-thermal appearance.
