Improved cosmological constraints on the curvature and equation of state of dark energy

Nana Pan, Yungui Gong, Yun Chen +1

We apply the Constitution compilation of 397 supernova Ia, the baryon acoustic oscillation measurements including the $A$ parameter, the distance ratio and the radial data, the fiv…

Using a phenomenological model to test the coincidence problem of dark energy

Yun Chen, Zong-Hong Zhu, J. S. Alcaniz +1

By assuming a phenomenological form for the ratio of the DE and DM densities $ρ_{X} \propto ρ_{m} a^{ξ}$ (Dalal et al.2001), we discuss the cosmic coincidence problem in light of curren…
