Prompt TeV Emission from Cosmic Rays Interacting with Stellar Wind in Gamma Ray Bursts
نویسندگان
چکیده
Cosmic ray protons accelerated in the internal shocks of a long duration gamma ray burst can escape the fireball by converting to neutrons. Hadronic interactions of these neutrons inside a stellar wind bubble created by the progenitor star will produce TeV gamma rays via neutral meson decay and synchrotron radiation by charged pion-decay electrons in the wind magnetic field. Such gamma rays may be observable from nearby gamma ray bursts by currently running and upcoming ground-based detectors.

Prompt TeV Emission from Cosmic Rays Accelerated by Gamma Ray Bursts Interacting with Surrounding Stellar Wind
Protons accelerated in the internal shocks of a long duration gamma ray burst can escape the fireball as cosmic rays by converting to neutrons. Hadronic interactions of these neutrons inside a stellar wind bubble created by the progenitor star will produce TeV gamma rays via neutral meson decay and synchrotron radiation by charged pion-decay electrons in the wind magnetic field. Such gamma rays...
متن کاملPrompt Gev-tev Emission of Gamma-ray Bursts Due to High-energy Protons, Muons and Electron-positron Pairs
In the framework of the internal shock scenario, we model the broadband prompt emission of gamma-ray bursts (GRBs) with emphasis on the GeV-TeV bands, utilizing Monte Carlo simulations that include various processes associated with electrons and protons accelerated to high energies. While inverse Compton emission from primary electrons is often dominant, different proton-induced mechanisms can ...
متن کاملUltrahigh Energy Cosmic Rays and Prompt TeV Gamma Rays from Gamma Ray Bursts
Gamma Ray Bursts (GRBs) have been proposed as one possible class of sources of the Ultrahigh Energy Cosmic Ray (UHECR) events observed up to energies >∼ 10 eV. The synchrotron radiation of the highest energy protons accelerated within the GRB source should produce gamma rays up to TeV energies. Here we briefly discuss the implications on the energetics of the GRB from the point of view of the d...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE γ-ray emission from PWNe interacting with molecular clouds
We consider a situation in which a pulsar (and its nebula) is formed inside or close to a high density regions of a molecular cloud. We apply a recent model for the gamma radiation of pulsar wind nebulae (PWN), which includes not only radiation processes due to injected leptons but also processes due to injection of relativistic hadrons, in order to calculate the expected γ-ray emission from su...
متن کاملPrompt High-Energy Emission from Proton-Dominated Gamma-Ray Bursts
The prompt emission of gamma-ray bursts (GRBs) is widely thought to be radiation from accelerated electrons, but an appreciably larger amount of energy could be carried by accelerated protons, particularly if GRBs are the sources of ultra-high-energy cosmic rays (UHECRs). We model the expected photon spectra for such “proton-dominated” GRBs in the internal shock scenario through Monte Carlo sim...
