Résumé: Gamma-Ray Bursts (GRBs), the most powerful explosions since the formation of the Universe, are unique cosmic events. Lasting from a few milliseconds to several minutes, they shine hundreds of times brighter than a typical supernova, the ultimate end of a massive star, and about a million trillion times as bright as the Sun. There is roughly a GRB detection once a day from wholly random sky directions. It is now widely accepted that GRBs are produced when a massive star undergoes core collapse or when two compact objects merge (e.g. neutron star - neutron star, black hole - neutron star). Due to the extreme luminosity of the multi-wavelength emission, they are now considered as one of the best ways to probe the dawn of the Universe.

An international school aimed at improving our knowledge of the GRB phenomena will take place in Cargèse in May 2010. Other topics to be covered are the unveiling of the nature of the early Universe and the preparation of the next generation of dedicated instruments. The school will be open to the entire scientific community. The school will be based primarily on in-depth lectures, with the remaining time available for shorter contributions from participants.

Résumé: The scientific aim of this school is to show how the new generation of data will allow to look for signatures characterizing the models of the early universe. The school will cover the physics of the cosmic microwave background, with particular emphasis on new aspects which are the most relevant to the confrontation of theories with observations. In particular :
