| Popis: | Gamma-Ray Burst (GRB) prompt emission contains information that can be used to infer structure of the relativistic outflow. Spectral lags, the Internal Luminosity Function (ILF), and Color-Color Diagrams are attributes that provide diagnositcs with which jet structure can be studied. These attributes help delineate properties of internal shocks originating in the large Lorentz factor, tightly-beamed central core of the jet and external shocks resulting when the jet slows down by decelerating into the external medium. The external shock signature has a smaller Lorentz factor and a larger beaming angle than the central jet core, yet both components are present in the prompt emission of some GRBs. |
