Constraints on a $\varphi$CDM model from strong gravitational lensing and updated Hubble parameter measurements

Yun Chen, Chao-Qiang Geng, Shuo Cao +2

We constrain the scalar field dark energy model with an inverse power-law potential, i.e., $V(\varphi )\propto {\varphi }^{-\alpha }$ ($\alpha >0$), from a set of recent cosmological observations by compiling…
