Dissipative fluid in Brans-Dicke theory and late time acceleration

Year: 2001

Type: article

Abstract: We investigate the possibility of having a late time accelerated expansion phase for the universe. We use a dissipative fluid in Brans-Dicke (BD) theory for this purpose. The model does not involve any potential for the BD scalar field. We obtain the best fit values for the different parameters in our model by comparing our model predictions with SNIa data and also with the data from the ultracompact radio sources.
