Fitting Supernovae and Gamma Ray Bursts Data Model 

written by Jacob Moldenhauer, Keenan Stone, Zeke Shuler, and Larry Engelhardt

The 1998 discovery of the cosmic acceleration with supernovae was recently awarded the 2011 Nobel Prize in Physics.  Gamma-Ray Bursts (GRB) support this accelerated expansion of the universe (cosmic acceleration) at high redshifts up to z=8.1. The simulation allows users to compare and fit theoretical models of cosmology with recent gamma-ray bursts data sets to confirm the accelerated expansion of the universe. This modeling allows the user to vary cosmological parameters within a particular class of dark energy cosmological models to fit a particular cosmological data set.  The user can plot several theoretical curves with the data to compare different models.  The values of these parameters, for a particular model, determine the physical description and evolution of the universe.

The EJS Fitting Cosmological Data GRB model was created using Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_FittingCosmologicalDataGRB.jar file will run the program if Java is installed.  You can modify this simulation if you have EJS by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
