Cosmologia no séc. XXI: um estudo na linha de 21 cm via Ciência do Radiotelescópio BINGO.

Abstract

The dark energy is the component responsible for the accelerated expansion of the Universe and it’s the greatest contributor to its energy content. A path to study it is through cosmological probes, such as: Type Ia Supernovae, Cosmic Microwave Background and Baryon Acoustic Oscillations. The study of Baryon Acoustic Oscillations measurements, in turn, can be performed by intensity mapping of the 21 cm radiation of cold neutral hydrogen atom. This is the main scientific objective of the BINGO radio telescope, under construction in the State of Paraíba,Brazil. Thus, the main objective of this dissertation is the study and to understand the 21 cm Cosmology, besides, we intend to understand the methods necessary to restrict the cosmological parameters, such as: the Hubble constant and the dark energy equation of state. Moreover, as a practical objective, we intend to perform computer simulations using Python language. Such simulations can be used to build maps and power spectra of the neutral hydrogen, with an emphasis on tomographic methodology, in the redshift range, which will also be relevant for BINGO.
