We study the constraint on deceleration parameter q from the recent SNela Gold dataset and observational Hubble data by using a model-independent deceleration parameter q(z) = 1/2 - a/(1 + z)^b under the flve-dim...

We investigate the constraints on a generalized Chaplygin gas (GCG) model using the gold sample type-Ia supernovae (She Ia) data, the new Supernova Legacy Survey (SNLS) Sne Ia data and the size of baryonic acous...

Jupiter's aurora exhibits three distinct regions: the satellite footprint emissions, the main oval emissions and all polar emissions. As the case of the Earth, the auroral morphology contains both qualitative and qu...

Using the evolution history of the universe, one can make constraint on the parameter space of dynamic dark energy models. We discuss two different parameterized dark energy models. Our results further restrict the co...
Supported by the Special Funds for Major State Basic Research Programme of China and the National Natural Science Foundation of China under Grant No 10273019.It is my great pleasure to thank Professary material.Thanks are also given to Professor Y-X.Gui for his helpful suggestion and discussion.
We investigate how the local and global metrics are connected in an ideal model of spacetime where the local system is assumed to be highly symmetric and the cosmological matter is kept away from the local system and ...
