Fitting Cosmological Data Package
written by Jacob Moldenhauer, Keenan Stone, Zeke Shuler, and Larry Engelhardt
The EJS Fitting Cosmological Data 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, and the CMB 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 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_CosmoEJS.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.

Cosmological Observation Data
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 …
