Testing the FLRW metric with the Hubble and transversal BAO measurements
Min Wang, Xiangyun Fu, Bing Xu +2
The cosmological principle is one of the fundamental assumptions of the standard model of Cosmology (SCM), and it allow us to describe cosmic distances and clocks by using the Frie…
Einstein-Gauss-Bonnet gravity coupled to bumblebee field in four dimensional spacetime
Chikun Ding, Xiongwen Chen, Xiangyun Fu
We study Einstein-Gauss-Bonnet gravity coupled to a bumblebee field which leads to a spontaneous Lorentz symmetry breaking in the gravitational sector. We obtain an exact black hol…
Probing the cosmic opacity from Future Gravitational Wave Standard Sirens
Lu Zhou, Xiangyun Fu, Zhaohui Peng +1
In this work, using the Gaussian Process, we explore the potentiality of future gravitational wave (GW) measurement to probe cosmic opacity through comparing its opacity-free lumin…
Testing Cosmic Distance-Duality Relation from Future Gravitational Wave Standard Sirens
Xiangyun Fu, Lu Zhou, Jun Chen
A validation of the cosmic distance-duality relation (CDDR) is crucial because any observational departure from it could be a signal of new physics. In this work, we explore the po…
Testing the Distance-Duality Relation from Strong Gravitational Lensing, Type Ia Supernovae and Gamma-Ray Bursts Data up to redshift
Xiangyun Fu, Pengcheng Li
In this paper, we perform a cosmological model-independent test of the cosmic distance-duality relation (CDDR) in terms of the ratio of angular diameter distance (ADD) $D=D_{\rm A}…
BSW process of the slowly evaporating charged black hole
Liancheng Wang, Feng He, Xiangyun Fu
In this paper, we study the BSW process of the slowly evaporating charged black hole. It can be found that the BSW process will also arise near black hole horizon when the evaporat…
The growth of matter perturbations in the f(T) gravity
Xiangyun Fu, Puxun Wu, Hongwei Yu
In this paper, we study the growth index of matter density perturbations for the power law model in gravity. Using the parametrization for the gr…
The growth factor of matter perturbations in an f(R) gravity
Xiangyun Fu, Puxun Wu, Hongwei Yu
The growth of matter perturbations in the model proposed by Starobinsky is studied in this paper. Three different parametric forms of the growth index are considered respect…
A parametrization for the growth index of linear matter perturbations
Puxun Wu, Hongwei Yu, Xiangyun Fu
We propose a parametrization for the growth index of the linear matter perturbations, . The growth factor of the perturbations parameterized as i…
The growth of linear perturbations in the DGP model
Xiangyun Fu, Puxun Wu, Hongwei Yu
We study the linear growth of matter perturbations in the DGP model with the growth index as a function of redshift. At the linear approximation: …
Density pertubation of unparticle dark matter in the flat Universe
Songbai Chen, Xiangyun Fu, Jiliang Jing
The unparticle has been suggested as a candidate of dark matter. We investigated the growth rate of the density perturbation for the unparticle dark matter in the flat Universe. Fi…
Dynamics of interacting phantom scalar field dark energy in Loop Quantum Cosmology
Xiangyun Fu, Hongwei Yu, Puxun Wu
We study the dynamics of a phantom scalar field dark energy interacting with dark matter in loop quantum cosmology (LQC). Two kinds of coupling of the form (case I)…
