Fast Radio Burst Cosmology: Hubble Tension and Dark Energy
Fayin Wang, Xuandong Jia, Daohong Gao +1
Fast radio bursts (FRBs) are luminous, millisecond-duration extragalactic radio transients that have emerged as a powerful, complementary cosmological probe for investigating the l…
New constraints on cosmic anisotropy from galaxy clusters using an improved dipole fitting method
Jianping Hu, Chao Geng, Xuandong Jia +3
The cosmological principle, as the cornerstone of the standard cosmological model, requires that the Universe be homogeneous and isotropic on large scales. As a fundamental assumpt…
Constraints on transition redshift utilizing the latest H(z) measurements and comments on the Hubble tension
Jianping Hu, Xuandong Jia, DaoHong Gao +3
The motivation of this paper is to obtain reliable constraints of transition redshift () and, in combination with the evolution of the Hubble constant () that could…
Testing cosmic anisotropy with Pade approximation and Pantheon+ sample
Jianping Hu, Jian Hu, Xuandong Jia +2
Cosmography can be used to constrain the kinematics of universe in a model-independent way. In this work, we attempted to combine the Pad approximations with the lat…
