    Constraints on active and sterile neutrinos in an interacting dark energy cosmology

    We investigate the impacts of dark energy on constraining massive (active/sterile) neutrinos in interacting dark energy (IDE) models by using the current observations. We employ two typical IDE models, the int...

    Exploring neutrino mass and mass hierarchy in interacting dark energy models

    We investigate how the dark energy properties impact the constraints on the total neutrino mass in interacting dark energy (IDE) models. In this study, we focus on two typical interacting dynamical dark energy...

    Models of vacuum energy interacting with cold dark matter: Constraints and comparison

    In this paper, we investigate the observational constraints on the scenario of vacuum energy interacting with cold dark matter. We consider eight typical interaction forms in such an interacting vacuum energy ...

    No evidence for the evolution of mass density power-law index γ from strong gravitational lensing observation

    In this paper, we consider the singular isothermal sphere lensing model that has a spherically symmetric power-law mass dis- tribution ρtot(r) ~ r-γ. We investigate whether the mass density power-law index γ is c...
