GRB 030329: 3 years of radio afterglow monitoring.
Radio observations of gamma-ray burst (GRB) afterglows are essential for our understanding of the physics of relativistic blast waves, as they enable us to follow the evolution of GRB explosions much longer than the afterglows in any other wave band. We have performed a 3-year monitoring campaign of GRB 030329 with the Westerbork Synthesis Radio Telescopes and the Giant Metrewave Radio Telescop...
متن کاملRadio Observations of the Afterglow of GRB 030329
We present the results of the radio observations of the afterglow of GRB 030329 with the Nobeyama 45-m telescope. The observations were made at 23.5 GHz, 43 GHz, and 90 GHz. The light curves show steep decline after constant phase. The start time of the decline depends on frequency. Namely, the decline started earlier at higher frequency. The spectrum has a peak at mm wavelength range. The peak...
متن کاملModeling the Optical Afterglow of GRB 030329
The best-sampled afterglow light curves are available for GRB 030329. A distinguishing feature of this event is the obvious rebrightening at around 1.6 days after the burst. Proposed explanations for the rebrightening mainly include the two-component jet model and the refreshed shock model, although a sudden density-jump in the circumburst environment is also a potential choice. Here we reexami...
متن کاملRadio, millimeter and optical monitoring of GRB 030329 afterglow: constraining the double jet model
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 1280 MHz has been carried out using the GMRT for more than a year. Simultaneous millimeter observations at 90 GHz and 230 GHz have been obtained from the Swedish-ESO Submillimeter Telescope (SEST) and the IRAM-P...
متن کاملThe X - ray afterglow of GRB 030329
the date of receipt and acceptance should be inserted later Abstract. We report on XMM-Newton and Rossi-XTE observations of the bright (fluence ∼ 10 −4 erg cm −2) and nearby (z=0.1685) Gamma-Ray Burst GRB030329 associated to SN2003dh. The first Rossi-XTE observation, 5 hours after the burst, shows a flux decreasing with time as a power law with index 0.9±0.3. Such a decay law is only marginally...
