CALDERA-CABRAL, G.A  y  URENA-LOPEZ, L.A. Materia y energía oscuras, ¿que son?. Rev. mex. fis. [online]. 2007, vol.53, suppl.4, pp.17-21. ISSN 0035-001X.

One of the most important problems in modern cosmology is the determination of the nature of dark matter and dark energy. We present a summary of the observational evidence for the existence of dark matter, and we make a revision of some of the candidates that appear in the literature. Likewise, we describe dynamical models for dark energy in the case of Quintessence and Phantom energy.

Palabras llave : Cosmology; dark matter; dark energy.
