Description
Cosmic Microwave Background radiation (CMB) is considered as first light that travelled freely through space after the Big Bang. After probes like COBE, WMAP and Planck, it was confirmed that temperature of the CMB is not uniform. Computing power spectrum for given cosmological model one can determine cosmological parameters of the Universe by comparing it to the observed power spectrum. In the talk I will present methods and approximations used to create program to compute CMB power spectrum and talk about results for different cosmological models.
