Abstract (from CDS):

We present radio, millimeter and optical observations of the afterglow of GRB 030329. UBVRCIC photometry is presented for a period of 3-h to 34-days after the burst. Radio monitoring at 1280MHz has been carried out using the GMRT for more than a year. Simultaneous millimeter observations at 90GHz and 230GHz have been obtained from the Swedish-ESO Submillimeter Telescope (SEST) and the IRAM-PdB interferometer over more than a month following the burst. We use these data to constrain the double jet model proposed by Berger et al. (2003Natur.426..154B) for this afterglow. We also examine whether instead of the two jets being simultaneously present, the wider jet could result from the initially narrow jet, due to a fresh supply of energy from the central engine after the ``jet break''.
