Inverse Compton X-ray Flare from GRB Reverse Shock
نویسندگان
چکیده
We study synchrotron self-inverse Compton radiation from a reverse-shocked fireball. If the inverse Compton process dominates the cooling of shocked electrons, an X-ray flare produced by the first order Compton scattering would emerge in the very early afterglow phase, with the bulk of the shock energy radiated in the second order scattering component at 10-100 MeV. The dominance of inverse Compton cooling leads to the lack of prompt optical flashes. Subject headings: gamma rays: bursts — shock waves — radiation mechanisms: nonthermal

GRB050904 is very interesting since it is by far the most distant GRB event known to date(z = 6.29). It was reported that during the prompt high energy emission phase, a very bright optical flare was detected, and it was temporal coincident with an X-ray flare. Here we use two models to explain the optical flare, One is the “late internal shock model”, in which the optical flare is produced by ...

متن کاملSub-GeV flashes in γ−ray burst afterglows as probes of underlying bright far-ultraviolet flares
Bright optical and X-ray flares have been observed in many Gamma-ray Burst (GRB) afterglows. These flares have been attributed to late activity of the central engine. In most cases the peak energy is not known and it is possible and even likely that there is a significant far-ultraviolet component. These far-ultraviolet photons escape our detection because they are absorbed by the neutral hydro...
متن کاملGRB early optical flash from internal shock : application to GRB 990123 , GRB 041219 a and GRB 060111 b
With the successful launch of the Swift Gamma-Ray Burst Explorer, people expected the prompt optical flash like GRB990123 would be easily detected. However the fact that early optical flash have not been detected for a number of GRBs indicates the reverse shock must be suppressed. Here we explore the possibility that the optical flash may arise from the internal shock. We find that, under certa...
