GRB 050315: A step in the proof of the uniqueness of the overall GRB structure
نویسندگان
چکیده
Using the Swift data of GRB 050315, we progress in proving the uniqueness of our theoretically predicted Gamma-Ray Burst (GRB) structure as composed by a proper-GRB, emitted at the transparency of an electron-positron plasma with suitable baryon loading, and an afterglow comprising the “prompt radiation” as due to external shocks. Detailed light curves for selected energy bands are theoretically fitted in the entire temporal region of the Swift observations ranging over 106 seconds.

Discovery of an Afterglow Extension of the Prompt Phase of Two Gamma Ray Bursts Observed by Swift
BAT and XRT observations of two recent well-covered GRBs observed by Swift, GRB 050315 and GRB 050319, show clearly a prompt component joining the onset of the afterglow emission. By fitting a power law form to the γ−ray spectrum, we extrapolate the time dependent fluxes measured by the BAT, in the energy band 15 − 350 keV, into the spectral regime observed by the XRT 0.2 − 10 keV, and examine ...
متن کاملPhysical processes shaping GRB X-ray afterglow lightcurves: theoretical implications from the Swift XRT observations
With the successful launch of the Swift Gamma-ray Burst Explorer, a rich trove of early X-ray afterglow data has been collected by its on-board X-Ray Telescope (XRT). Some interesting features are emerging, including a distinct rapidly decaying component preceding the conventional afterglow component in many sources, a shallow decay component before the more “normal” decay component observed in...
متن کاملSwift Observations of the X-ray–bright Grb 050315
This paper discusses Swift observations of the -ray burst GRB 050315 (z 1⁄4 1:949) from 80 s to 10 days after the onset of the burst. The X-ray light curve displayed a steep early decay (t ) for 200 s and several breaks. However, both the prompt hard X-ray/ -ray emission (observed by the BAT) and the first 300 s of X-ray emission (observed by the XRT) can be explained by exponential decays, wit...
متن کاملDISCOVERY AND REDSHIFT OF AN OPTICAL AFTERGLOW IN 71 SQUARE DEGREES: iPTF13BXL AND GRB 130702A
We report the discovery of the optical afterglow of the γ-ray burst (GRB) 130702A, identified upon searching 71 deg2 surrounding the Fermi Gamma-ray Burst Monitor (GBM) localization. Discovered and characterized by the intermediate Palomar Transient Factory, iPTF13bxl is the first afterglow discovered solely based on a GBM localization. Real-time image subtraction, machine learning, human vetti...
