Deconfinement phase transition in hybrid neutron stars from the Brueckner theory with three-body forces and a quark model with chiral mass scaling
G. X. Peng, A. Li, U. Lombardo
We study the properties of strange quark matter in equilibrium with normal nuclear matter. Instead of using the conventional bag model in quark sector, we achieve the confinement b…

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…
Dynamical vacuum energy, holographic quintom, and the reconstruction of scalar-field dark energy
Xin Zhang
When taking the holographic principle into account, the vacuum energy will acquire dynamical property that its equation of state is evolving. The current available observational da…
Two-Field Quintom Models in the w-w' Plane
Zong-Kuan Guo, Yun-Song Piao, Xinmin Zhang +1
The w-w' plane, defined by the equation of state parameter for the dark energy and its derivative with respect to the logarithm of the scale factor, is useful to the study of class…
Noncommutative chaotic inflation and WMAP three year results
Xin Zhang, Feng-Quan Wu
Noncommutative inflation is based upon the consideration of some effects of the space-time uncertainty principle motivated by ideas from string/M theory. The CMB anisotropies may c…

We have studied the uncertainty on the determination of the dark energy equation of state due to a non-vanishing spatial curvature by considering some fundamental observables. We d…
Constraints on the DGP Model from Recent Supernova Observations and Baryon Acoustic Oscillations
Zong-Kuan Guo, Zong-Hong Zhu, J. S. Alcaniz +1
Although there is mounting observational evidence that the expansion of our universe is undergoing a late-time acceleration, the mechanism for this acceleration is yet unknown. In…
Modified equation of state, scalar field, and bulk viscosity in Friedmann universe
J. Ren, X. H. Meng
A generalized dynamical equation for the scale factor of the universe is proposed to describe the cosmological evolution, of which the CDM model is a special case. It also provi…
Towards Determination of the Initial Flavor Composition of Ultrahigh-energy Neutrino Fluxes with Neutrino Telescopes
Zhi-zhong Xing, Shun Zhou
We propose a simple but useful parametrization of the flavor composition of ultrahigh-energy neutrino fluxes produced from distant astrophysical sources: $ϕ^{}_e : ϕ^{}_μ: ϕ^{}_τ=…
Is PSR B0943+10 a low-mass quark star?
Y. L. Yue, X. H. Cui, R. X. Xu
A recent X-ray observation has shown that the radio pulsar PSR B0943+10, with clear drifting subpulses, has a much smaller polar cap area than that of conventional pulsars with mas…
