REYES-IBARRA, M.J  y  URENA-LOPEZ, L.A. La radiación del fondo cósmico. Rev. mex. fis. [online]. 2007, vol.53, suppl.4, pp.133-136. ISSN 0035-001X.

Observations on the anisotropies of the Cosmic Microwave Background have become a fundamental tool in Cosmology. We present a brief description of the mathematical formulae that is necessary to understand the evolution of the anisotropies, and how their power spectrum gives us information about the evolution and composition of the universe.

Palabras llave : Cosmology; cosmic microwave background; cosmological perturbations.
