Oscilações Acústicas de Bárions
Abstract in Portuguese
As nuvens de hidrogênio neutro presentes no espaço intergaláctico seguem o espectro de potência da matéria. Ao observamos a linha de 21 cm emitida é possível detectar a escala das oscilações acústicas de bárions. O BINGO é um radiotelescópio que permitirá a análise dessa emissão em baixos redshifts (0.13 < z < 0.48), onde a energia escura tem papel importante. No contexto do BINGO faremos a análise das oscilações acústicas, usaremos a escala do BAO (Baryon Acústic Oscilations) advinda dessa análise e o método de matriz de Fisher para determinarmos a precisão com que podemos medir os parâmetros cosmológicos associados à energia escura no contexto da parametrização CPL, e nos modelos de interação fenomenológica do setor escuro.

Abstract in English
The neutral hydrogen clouds present in the intergalactic medium trace the matter power spectrum. When observing the 21 cm line emitted it is possible to detect the baryons acustic oscilations. The BINGO is a radio telescope that will allow the analysis of this emission in low redshifts (0.13 < z < 0.48), where dark energy plays an important role. In BINGO context we will perform the acoustic oscillations analysis, we will use the BAO (Baryon Acustic Oscillations) scale derived from this analysis and the Fisher matrix method to determine the precision with which we can measure the cosmological parameters associated with dark energy in the CPL parameterization, and in the phenomenological interaction models of dark sector.
