✍️ About : MCMC, or EMCEE, is the most commonly used sampler to fit the cosmological model with the various data sets to understand the fundamentals of universe, for example- the Hubble constant, the matter density, and the geometry of the universe. As the universe is itself a highly dynamic playground, obtaining data is a cumbersome task. Although we have various data sets, the error in the data is huge, and because of the unknown variables, one is required to heavily rely on statistical techniques to establish the viability of the cosmological model. Therefore, understanding data analysis in cosmology has become one of the central themes of this game. However, just writing basic code in python won't do the job, because python is not as fast as C or C++. Therefore, optimizing the cosmological algorithm becomes too important in this case. In this video, I have shown the optimization of the algorithm and achieved MCMC 100 times faster than conventional coding. I have used CYTHON and PYTHON to optimize my code to fit the LambdaCDM model with 43 Hubble data sets. Here I am listing my papers that you can see and also attaching the GitHub repository link where you can find this code: https://github.com/sleonardokap/cosmo...
