Abstract | presentamos neste artigo um breve panorama da cosmologia de 21 cm, baseada no estudo da transição hiperfinado spin do elétron no átomo de hidrogênio neutro (HI). A distribuição de HIé um dos traçadores da aglutinaçãode matéria e da formação de estruturas e é, possivelmente, a única forma de observar o universo antes dareionização, ocorrida em20&z&6. Apresentamos a técnica de radioastronomia utilizada para medir adistribuição de HI, conhecida como mapeamento de intensidade, e os requisitos instrumentais necessários pararealizá-lo e produzir um levantamento de HIem rádio, ao longo de um intervalo deredshifts2,5&z&0,1.Nesse contexto, apresentamos o radiotelescópio BINGO, que está sendo construído no Brasil e foi projetadopara medir oscilações acústicas de bárions no universo próximo (0,127≤z≤0,449) usando o mapeamento deintensidade da transição de 21 cm. ABSTRACT: In this article we present a brief overview of the 21 cm cosmology, based on the study of the hyperfine spintransition of the electron in the neutral hydrogen atom (HI). The hydrogen distribution is one of the tracers ofthe matter clustering and formation of structures and it is possibly the only way to observe the Universe beforereionization, which occurred in20&z&6. We present the radio astronomy technique used to measure thedistribution of HI, known as intensity mapping, and the instrumental requirements needed to perform it andproduce a HIsurvey in radio, over an interval ofredshifts2.5&z&0.1. In this context, we present the BINGOradio telescope, which is being built in Brazil and was designed to measure acoustic oscillations of baryons inthe nearby Universe (0.127≤z≤0.449) using intensity mapping of the 21 cm transition. |
