      Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae(1) that are more luminous than average(2-5) and that eject material at very high velocities. Less-luminous supernovae were not hitherto known to ...

      Aims. We present early optical spectroscopy of the afterglow of the gamma-ray burst GRB060206 with the aim of determining the metallicity of the GRB absorber and the physical conditions in the circumburst medium. We also ...
