Cosmological constant and late transient acceleration of the universe in the Horava-Witten Heterotic M-Theory on S^{1}/Z_{2}
Yungui Gong, Anzhong Wang, Qiang Wu
Orbifold branes are studied in the framework of the 11-dimensional Horava-Witten heterotic M-Theory. It is found that the effective cosmological constant can be easily lowered to i…
Dark energy and cosmic curvature: Monte-Carlo Markov Chain approach
Yungui Gong, Qiang Wu, Anzhong Wang
We use the Monte-Carlo Markov Chain method to explore the dark energy property and the cosmic curvature by fitting two popular dark energy parameterizations to the observational da…
The generalized second law of thermodynamics in the accelerating universe
Jia Zhou, Bin Wang, Yungui Gong +1
We show that in the accelerating universe the generalized second law of thermodynamics holds only in the case where the enveloping surface is the apparent horizon, but not in the c…
Testing the viability of the interacting holographic dark energy model by using combined observational constraints
Chang Feng, Bin Wang, Yungui Gong +1
Using the data coming from the new 182 Gold type Ia supernova samples, the shift parameter of the Cosmic Microwave Background given by the three-year Wilkinson Microwave Anisotropy…
Energy conditions and current acceleration of the universe
Yungui Gong, Anzhong Wang
The energy conditions provide a very promising model-independent study of the current acceleration of the universe. However, in order to connect these conditions with observations,…
Friedmann Equations and Thermodynamics of Apparent Horizons
Yungui Gong, Anzhong Wang
With the help of a masslike function which has dimension of energy and equals to the Misner-Sharp mass at the apparent horizon, we show that the first law of thermodynamics of the…
