Physical Parameters Of The Relativistic Shock Waves In GRBs: The Case Of 30 GRBs

TL;DR

This study uses a modified internal shock model to analyze 30 GRBs, deriving physical parameters of relativistic shells that align with theoretical predictions, and explores their connection to GRB phenomena.

Contribution

It provides a detailed fitting of GRB light and spectral curves using a modified shock model, extracting physical parameters consistent with prior theories.

Findings

Relativistic shell parameters match earlier predictions

Model fitting accurately reproduces observed GRB light curves

Connections between physical parameters and GRB mechanisms are discussed

Abstract

Using the modified internal shock wave model we fit the gamma ray burst (GRB) light and spectral curves of 30 GRBs observed with BATSE. From the best fitting we obtain basic parameters of the relativistic shells which are in good agreement with predictions given earlier. We compare measured GRB parameters with those obtained from the model and discuss connections between them in the frame of the physical processes laying behind GRB events.
