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