Constraining neutrino mass in dynamical dark energy cosmologies with the logarithm parametrization and the oscillating parametrization
Tian-Ying Yao, Rui-Yun Guo, Xin-Yue Zhao
We constrain two dynamical dark energy models that are parametrized by the logarithm form of and the oscillating form of…
Exploration of interacting dynamical dark energy model with interaction term including the equation-of-state parameter: alleviation of the tension
Rui-Yun Guo, Lu Feng, Tian-Ying Yao +1
We explore a scenario of interacting dynamical dark energy model with the interaction term including the varying equation-of-state parameter . Using the data combination of…
Cosmological search for sterile neutrinos after Planck 2018
Lu Feng, Rui-Yun Guo, Jing-Fei Zhang +1
Sterile neutrinos can affect the evolution of the universe, and thus using the cosmological observations can search for sterile neutrinos. In this work, we use the cosmic microwave…
Inflation model selection revisited after a 1.91% measurement of the Hubble constant
Rui-Yun Guo, Jing-Fei Zhang, Xin Zhang
The recent local measurement of the Hubble constant based on the distance-ladder method has reached a precision, but this result is in tension with the early-universe meas…
Revisit of constraints on dark energy with Hubble parameter measurements including future redshift drift observations
Yan Liu, Rui-Yun Guo, Jing-Fei Zhang +1
We investigate whether the current Hubble parameter measurements could help improve the constraints on dark energy on the basis of the mainstream cosmological probes includi…
Dark energy versus modified gravity: Impacts on measuring neutrino mass
Ming-Ming Zhao, Rui-Yun Guo, Dong-Ze He +2
In this paper, we make a comparison for the impacts of smooth dynamical dark energy, modified gravity, and interacting dark energy on the cosmological constraints on the total mass…
Can the tension be resolved in extensions to CDM cosmology?
Rui-Yun Guo, Jing-Fei Zhang, Xin Zhang
We wish to investigate whether there is an extension to the base CDM cosmology that can resolve the tension between the Planck observation of the cosmic microwave background ani…

Dark energy affects the Hubble expansion rate (namely, the expansion history) by an integral over . However, the usual observables are the luminosity distances or the…
Redshift drift constraints on f(T) gravity
Jia-Jia Geng, Rui-Yun Guo, Dong-Ze He +2
We explore the impact of the Sandage-Loeb (SL) test on the precision of cosmological constraints for gravity theories. The SL test is an important supplement to current cosm…
