Probing the sign-changeable interaction between dark energy and dark matter with current observations
Juan-Juan Guo, Jing-Fei Zhang, Yun-He Li +2
We consider the models of vacuum energy interacting with cold dark matter in this study, in which the coupling can change sigh during the cosmological evolution. We parameterize th…

Weighing neutrinos in the scenario of vacuum energy interacting with cold dark matter: application of the parameterized post-Friedmann approach
Rui-Yun Guo, Yun-He Li, Jing-Fei Zhang +1
We constrain the neutrino mass in the scenario of vacuum energy interacting with cold dark matter by using current cosmological observations. To avoid the large-scale instability p…
