13. Analise de eventos Centauro
Along its existence, the Brasil-Japan Collaboration for the Chacaltaya Emulsion Chamber Experiment has obtained important results in the fields of Cosmic Rays, High Energy and Particle Physics. One of these results is the observation of the atmospheric families known as Centauro type events. Its main characteristic is the predominance of the hadronic compone

14. The microwave background anisotropies: Observations
Most cosmologists now believe that we live in an evolving universe that has been expanding and cooling since its origin about 15 billion years ago. Strong evidence for this standard cosmological model comes from studies of the cosmic microwave background radiation (CMBR), the remnant heat from the initial fireball. The CMBR spectrum is blackbody, as pre

15. Cosmological implications of light element abundances: theory.
Primordial nucleosynthesis provides (with the microwave background radiation) one of the two quantitative experimental tests of the hot Big Bang cosmological model (versus alternative explanations for the observed Hubble expansion). The standard homogeneous-isotropic calculation fits the light element abundances ranging from 1H at 76% and 4He at 24% by mass
