Abstract

We present the scientific analysis of the GRB afterglow data obtained by the GROND, aseven-channel imager with four optical and three near-infrared detectors. Its uniquecapability to observe in all bands simultaneously, together with rapid triggering, precisephotometry and high temporal resolution, give us the opportunity to study light curves andspectral energy distributions of GRB afterglows in unprecedented detail. This isdemonstrated using the observations of three GRB afterglows that are used to put strongconstrains on the standard GRB fireball scenario.
