Reconstruction of the deceleration parameter and the equation of state of dark energy
Yungui Gong, Anzhong Wang
The new 182 gold supernova Ia data, the baryon acoustic oscillation measurement and the shift parameter determined from the Sloan Digital Sky Survey and the three-year Wilkinson Mi…
Thermodynamical properties of dark energy
Yungui Gong, Bin Wang, Anzhong Wang
We have investigated the thermodynamical properties of dark energy. Assuming that the dark energy temperature and considering that the volume of the Universe envelop…
Existence of black holes in Friedmann-Robertson-Walker universe dominated by dark energy
Zhong-Heng Li, Anzhong Wang
We study the existence of black holes in a homogeneous and isotropic expanding Friedmann-Robertson-Walker (FRW) universe dominated by dark energy. We show that black holes can exis…
Homothetic Self-Similar Solutions of the Three-Dimensional Brans-Dicke Gravity
G. A. Benesh, Anzhong Wang
All homothetic self-similar solutions of the Brans-Dicke scalar field in three-dimensional spacetime with circular symmetry are found in closed form.
Acceleration from M theory and Fine-tuning
Yungui Gong, Anzhong Wang
The compactification of M theory with time dependent hyperbolic internal space gives an effective scalar field with exponential potential which provides a transient acceleration in…
Observational constraints on the acceleration of the Universe
Yungui Gong, Anzhong Wang
We propose a new parametrization of the deceleration parameter to study its time-variation behavior. The advantage of parameterizing the deceleration parameter is that we do not ne…
