Overview
Numerical studies of Gamma-ray burst (GRB) afterglow jets reveal significant qualitative differences with simplified analytical models. We present an on-line library of synthetic afterglow light curves and broadband spectra for use in interpreting observational data. Light curves have been calculated for various physics settings such as explosion energy and circumburst structure, as well as differing jet parameters and observer angle and redshift. The light curves have been calculated from high-resolution 2D hydrodynamical simulations performed with the RAM adaptive-mesh refinement code and a detailed synchrotron radiation code.

DATASETS
|
Afterglow light curve data are available here. The datasets are subdivided by
publication. Preview light curve plots are provided, the datasets are
downloadable both in HDF5 format and simple text format. A readme.txt file
with additional information is provided as well as the python scripts that were
used in preparing the datasets and plots.
