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) theo ry for this purpose. The model does not involve any potential for the BD sc alar field. We obtain the best fit values fur the different parameters in o ur model by comparing our model predictions with SNIa data and also with th e data from the ultracompact radio sources.
