... Australia Telescope Steering Committee . ... Parkes radio telescope . ... Such a model can reproduce much of the observed late-time evolution of the radio flux density and spectral index (though recent results for SNб 1993J (van Dyk et al. 1994) show that the Chevalier model does not adequately describe the early behaviour of radio light curves for this supernova, perhaps due to variations in the mass-loss rate and clumping in the stellar wind, which are not yet accounted for in the model). ...

... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.€а Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.€а €аAlbert Einstein originally suggested its existence about 80 years ago.
