Testing nonstandard cosmological models with SNLS3 supernova data and other cosmological probes
Zhengxiang Li, Puxun Wu, Hongwei Yu
We investigate the implications for some nonstandard cosmological models using data from the first three years of the Supernova Legacy Survey (SNLS3), assuming a spatially flat uni…
The stability of the Einstein static state in gravity
Puxun Wu, Hongwei Yu
The stability of the Einstein static universe against the homogeneous scalar perturbations in gravity is analyzed. Both the spatial closed and open universes are considered.…
A Consistent Test of the Distance-Duality Relation with Galaxy Clusters and Type Ia Supernave
Nan Liang, Zhengxiang Li, Puxun Wu +3
We propose a new consistent method to test of the distance-duality (DD) relation which related angular diameter distances (DA) to the luminosity distances (DL) in a cosmology-indep…
Cosmological-model-independent tests for the distance-duality relation from Galaxy Clusters and Type Ia Supernova
Zhengxiang Li, Puxun Wu, Hongwei Yu
We perform a cosmological-model-independent test for the distance-duality (DD) relation , where and are the luminosity distance and angula…
