Measurements of the baryon acoustic oscillations (BAO or Baryon), as standard rulers, support the accelerated expansion of the universe (cosmic acceleration). This simulation compares the ratio of the sound horizon early in the evolution of the universe to similar features at late times in the structure of galaxy clusters. The simulation allows users to compare and fit theoretical models of cosmology with recent BAO 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 Baryon 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_FittingCosmologicalDataBaryon.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.
