Résumé:
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.
