چکیده
Gamma-ray burst sources with a high luminosity can produce electron-positron pair cascades in their environment as a result of back-scattering of a seed fraction of their original hard spectrum. The resulting spectral modifications offer the possibility of diagnosing not only the compactness parameter of the γ-ray emitting region but also the baryonic density of the environment external to the burst.

متن کاملClosure Relations for E Pair-signatures in Gamma-ray Bursts
We present recipes to diagnose the fireball of gamma-ray bursts (GRBs) by combining observations of e pair-signatures (the pair-annihilation line and the cutoff energy due to the pair-creation process). Our recipes are largely model-independent and extract information even from the non-detection of either pair-signature. We evaluate physical quantities such as the Lorentz factor, optical depth ...
متن کاملThe expected thermal precursors of gamma-ray bursts in the internal shock model
The prompt emission of gamma-ray bursts probably comes from a highly relativistic wind which converts part of its kinetic energy into radiation via the formation of shocks within the wind itself. Such ”internal shocks” can occur if the wind is generated with a highly non uniform distribution of the Lorentz factor. We estimate the expected photospheric emission of such a relativistic wind when i...
متن کاملPrecursors in Swift Gamma Ray Bursts with redshift
We study a sample of Gamma Ray Bursts detected by the Swift satellite with known redshift and that show a precursor in the Swift–BAT light curve. We analyse the spectrum of the precursors and compare them with the time integrated spectrum of the rest of the prompt emission. We find no clear correlation between the two slopes, and no clear tendency for the spectra of the precursors to be systema...
