    Conformally flat spherically symmetric cosmological models-revisited
    (2011-07-06) Pradhan, A.; Pandey, Om Prakash
    Conformally flat spherically symmetric cosmological models rep- resenting a charged perfect fluid as well as a bulk viscous fluid dis- tribution have been obtained. The cosmological constant Λ is found positive and is a decreasing function of time which is consistent with the recent supernovae observations. The physical and geometrical properties of the models are discussed.
