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…
Prospect for cosmological parameter estimation using future Hubble parameter measurements
Jia-Jia Geng, Rui-Yun Guo, Anzhong Wang +2
We constrain cosmological parameters using only Hubble parameter data and quantify the impact of future Hubble parameter measurements on parameter estimation for the most typical d…
Exploring neutrino mass and mass hierarchy in the scenario of vacuum energy interacting with cold dark matter
Rui-Yun Guo, Jing-Fei Zhang, Xin Zhang
We investigate the constraints on total neutrino mass in the scenario of vacuum energy interacting with cold dark matter. We focus on two typical interaction forms, i.e., $Q=βHρ_{\…
