The detection of 1.809 MeV gamma-ray line emission from the Cygnus X complex by the COMPTEL telescope is one of the most convincing proves of massive star...
We report rapid near-infrared observations of GRB 020819. We find that any afterglow was fainter than K'=19 only 9 hrs after the burst. We discuss if extinction...
