The EJS Fitting Cosmological Data DEDGP Launcher package includes several cosmological fitting simulations for five different observations of the expansion, all of which support a cosmic acceleration. The launcher allows users to choose which simulation to use to compare and fit theoretical models of cosmology with recent supernovae, gamma-ray bursts, the Hubble Parameter, baryon acoustic oscillations, Alcock-Paczynski, growth factor parameter and the cosmic microwave background radiation data sets to confirm the accelerated expansion of the universe. The simulations now includes dark energy (DE) and Dvali-Gabadadze-Porrati (DGP) classes of cosmological models. 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 DEDGP Launcher package was created using Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_CosmoEJSDEDGP.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.
Please note that this resource requires
at least version 1.6 of Java.

Here we give the details of observations and theoretical background included in CosmoEJS. We include recent supernovae (SNe) Type Ia surveys, gamma-ray bursts (GRB), the Hubble expansion rate parameter H(z), baryon acoustic oscillations (BAO), and the surface of the last scatttering of the cosmic microwave background (CMB) radiation.
