Does regenerated emission change the high-energy signal from gamma-ray burst afterglows?
We study regenerated high-energy emission from the gamma-ray burst (GRB) afterglows, and compare its flux with the direct component from the same afterglow. When the intrinsic emission spectrum extends to TeV region, these very high-energy photons are significantly absorbed by the cosmic infrared background (CIB) radiation field, creating electron/positron pairs; since these pairs are highly en...
متن کاملHigh-energy emission as a test of the prior emission model for gamma-ray burst afterglows
We study high-energy gamma-ray afterglow emission from gamma-ray bursts (GRBs) in the prior emission model, which is proposed to explain the plateau phase of the X-ray afterglow. This model predicts the high-energy gamma-ray emission when the prompt GRB photons from the main flow are up-scattered by relativistic electrons accelerated at the external shock due to the prior flow. The expected spe...
متن کاملOn the multiwavelength emission from Gamma Ray Burst afterglows
Aims. Drawing an analogy with Active Galactic Nuclei, we investigate the one-zone SSC model of Gamma Ray Bursts afterglows in the presence of electron injection and cooling both by synchrotron and SSC losses. Methods. We solve the spatially averaged kinetic equations which describe the simultaneous evolution of particles and photons, obtaining the multi-wavelength spectrum as a function of time...
متن کاملHigh energy afterglows and flares from Gamma-Ray Burst by Inverse Compton emission
We perform a detailed study of Inverse Compton (IC) emission for a fireball undergoing External Shock (ES) in either a uniform or a wind-like interstellar medium, and assess the relative importance of IC and synchrotron emission. We determine the primary model parameters driving the IC to synchrotron emission ratio in the case of a short duration central engine. We then investigate the case of ...
متن کاملHigh Energy Emission from the Prompt Gamma-Ray Burst
We study the synchrotron and synchrotron self-Compton (SSC) emission from internal shocks that are responsible for the prompt γ-ray emission in GammaRay Bursts (GRBs), and consider the relation between these two components, taking into account the high energy cutoff due to pair production and Thomson scattering. We find that in order for the peak energy of the synchrotron to be Ep ∼ 300 keV wit...
