%0 Journal Article %T Scalar Field as Dark Matter in the Universe %A T. Matos %A F. S. Guzman %A L. A. Urena-Lopez %J Physics %D 1999 %I arXiv %R 10.1088/0264-9381/17/7/309 %X We investigate the hypothesis that the scalar field is the dark matter and the dark energy in the Cosmos, wich comprises about 95% of the matter of the Universe. We show that this hypothesis explains quite well the recent observations on type Ia supernovae. %U http://arxiv.org/abs/astro-ph/9908152v2
