Constraints on holographic dark energy from X-ray gas mass fraction of galaxy clusters
Zhe Chang, Feng-Quan Wu, Xin Zhang
We use the Chandra measurements of the X-ray gas mass fraction of 26 rich clusters released by Allen et al. to perform constraints on the holographic dark energy model. The constra…

Cosmic ray threshold in an asymptotically dS spacetime
Zhe Chang, Shao-Xia Chen, Cheng-Bo Guan +1
We discuss the threshold anomaly in ultra-high energy cosmic ray physics by assuming that the matter world just be perturbation of a de Sitter universe, which is consistent with th…
