Delayed Flash from Counter Jet of Gamma Ray Burst
نویسندگان
چکیده
If the X-ray flash is the gamma ray burst (GRB) observed with the large viewing angle from the forward jet, we show that the emission from the counter jet should be observed as the delayed flash in the UV or optical band several hours to a day after the X-ray flash. If the distance is several tens of Mpc or so, i.e., similar to GRB980425, FUV-MAMA on HST/STIS or UVOT on Swift can observe the delayed flash, so that the collimated jets of the GRBs may be directly confirmed.

Delayed Flashes from Counter Jets of Gamma Ray Bursts
If X-ray flashes are due to the forward jet emissions from gamma ray bursts (GRBs) observed with large viewing angles, we show that a prompt emission from a counter jet should be observed as a delayed flash in the UV or optical band several hours to a day after the X-ray flash. Ultraviolet and Optical Telescope on Swift can observe the delayed flashes within ∼ 13 Mpc, so that (double-sided) jet...
متن کاملRebrightening of XRF 030723: Further Evidence for a Two-Component Jet in Gamma-Ray Burst
Optical afterglows from two-component jets under various configurations are investigated numerically. Generally, the light curve is characterized by a rapid rebrightening when the observer is off-axis with respect to the narrow component, with the amplitude and peak time depending on detailed parameters. We further show that the optical afterglow of XRF 030723, especially its notable and rapid ...
متن کاملA Global Test of a Quasi-universal Gamma-ray Burst Jet Model through Monte-carlo Simulations
The possibility that long gamma-ray burst (GRB) jets are structured receives growing attention recently, and we have suggested that most GRBs and their softer, less energetic fraternity, X-ray flashes (XRFs), can be understood within a quasi-universal structured jet picture, given that the jet structure of each individual burst is a Gaussian or similar function. Here we perform a global test on...

متن کاملTHE PROPAGATION AND ERUPTION OF RELATIVISTIC JETS FROM THE STELLAR PROGENITORS OF GRBs
New twoand three-dimensional calculations are presented of relativistic jet propagation and break out in massive Wolf-Rayet stars. Such jets are thought responsible for gamma-ray bursts. As it erupts, the highly relativistic jet core (3 to 5 degrees; Γ & 100) is surrounded by a cocoon of less energetic, but still moderately relativistic ejecta (Γ ∼ 15) that expands and becomes visible at larger...
