Simulations on High-z Long Gamma-Ray Burst Rate
Shu-Fu Qin, En-Wei Liang, Rui-Jing Lu +2
Since the launch of Swift satellite, the detections of high-z (z>4) long gamma-ray bursts (LGRBs) have been rapidly growing, even approaching the very early Universe (the record ho…
Exact solutions for shells collapsing towards a pre-existing black hole
Yuan Liu, Shuang Nan Zhang
The gravitational collapse of a star is an important issue both for general relativity and astrophysics, which is related to the well known "frozen star" paradox. This paradox has…
Modified clock inequalities and modified black hole lifetime
Rong-Jia Yang, Shuang Nan Zhang
Based on a generalized uncertainty principle, Salecker-Wigner inequalities are modified. When applied to black holes, they give a modified black hole lifetime: $T_{\rm MB}\sim\frac…
A Two-field Dilaton Model of Dark Energy
Nan Liang, ChangJun Gao, ShuangNan Zhang
We investigate the cosmological evolution of a two-field model of dark energy where one is a dilaton field with canonical kinetic energy and the other is a phantom field with a neg…
Significant foreground unrelated non-acoustic anisotropy on the one degree scale in WMAP 5-year observations
Bi-Zhu Jiang, Richard Lieu, Shuang-Nan Zhang +1
The spectral variation of the cosmic microwave background (CMB) as observed by WMAP was tested using foreground reduced WMAP5 data, by producing subtraction maps at the 1 a…
Determining the Distance of Cyg X-3 with its X-ray Dust Scattering Halo
Zhixing Ling, Shuang Nan Zhang, Shichao Tang
Using a cross-correlation method, we study the X-ray halo of Cyg X-3. Two components of dust distributions are needed to explain the time lags derived by the cross-correlation meth…
