Cosmological Applications of Pade Approximant
Hao Wei, Xiao-Peng Yan, Ya-Nan Zhou
As is well known, in mathematics, any function could be approximated by the Padé approximant. The Padé approximant is the best approximation of a function by a rational function of…
Cosmological Evolution of Einstein-Aether Models with Power-law-like Potential
Hao Wei, Xiao-Peng Yan, Ya-Nan Zhou
The so-called Einstein-Aether theory is General Relativity coupled (at second derivative order) to a dynamical unit time-like vector field (the aether). It is a Lorentz-violating t…
Indistinguishability of Warm Dark Matter, Modified Gravity, and Coupled Cold Dark Matter
Hao Wei, Jing Liu, Zu-Cheng Chen +1
The current accelerated expansion of our universe could be due to an unknown energy component with negative pressure (dark energy) or a modification to general relativity (modified…
Cosmological Constraints on Variable Warm Dark Matter
Hao Wei, Zu-Cheng Chen, Jing Liu
Although CDM model is very successful in many aspects, it has been seriously challenged. Recently, warm dark matter (WDM) remarkably rose as an alternative of cold dark matter (…
