Potential contributions of Pop III and intermediate-mass Pop II stars to cosmic chemical enrichment

Autor: Lia C. Corazza, Oswaldo D. Miranda, Carlos A. Wuensche

We propose a semi-analytic model that is developed to understand the cosmological evolution of the mean metallicity in the Universe. In particular, we study the contributions of Population III (Pop III) and Population II (Pop II) stars to the product

To recover the 21 cm hydrogen line, it is essential to separate the cosmological signal from the much stronger foreground contributions at radio frequencies. The BINGO radio telescope is designed to measure the 21 cm line and detect BAOs using the in

Arqueologia Cósmica com a radiação cósmica de fundo em microondas

Autor: Carlos Alexandre Wuensche de Souza, Thyrso Villela, Camilo Tello, Ivan Soares Ferreira

Publikováno v: Caderno Brasileiro de Ensino de Física, Vol 27, Iss 0, Pp 647-671 (2010)

A cosmologia é uma ciência relativamente jovem, e que permanentemente requer observações que sustentem as previsões teóricas dos cientistas que trabalham nessa área. A Radiação Cósmica de Fundo em microondas (RCFM) é uma das observações
