Constraining Chaplygin models using diffuse supernova neutrino background
Nan Yang, Junji Jia, Xionghui Liu +1
In this work, we examine the possibility of using the diffuse supernova neutrino background (DSNB) to test the Chaplygin gas (CG) models of the Universe. With a typical supernova r…

Existence and stability of circular orbits in general static and spherically symmetric spacetimes
Junji Jia, Jiawei Liu, Xionghui Liu +4
The existence and stability of circular orbits (CO) in static and spherically symmetric (SSS) spacetime are important because of their practical and potential usefulness. In this p…
