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

Abstract: Five decades since the first discovery of a gamma-ray burst (GRB), the prompt emission mechanism remains an open question. One promising candidate is that the high-energy emission originates from the photosphere, where the ejecta transitions from
opaque to optically thin. Hydrodynamical simulations of GRB jets show that shocks are likely to form below the photosphere and due to the high radiation pressure in the optically thick region, these shocks will be radiation mediated. In this talk, I will discuss
how such shocks alters the shape of the spectrum released at the photosphere. Furthermore, I present a model that we have developed, which hopefully can explain a wide variety of GRB prompt emission spectra. <br>
