Test of the cosmic distance duality relation for arbitrary spatial curvature

no code implementations14 Jan 2021 Jin Qin, Fulvio Melia, Tong-Jie Zhang

We parametrize the CDDR using eta(z)=1 + eta_0 z, 1 + eta_1 z + eta_2 z^2 and 1 + eta_3 z/(1+z), and consider both the SIS and non-SIS lens models for the strong lensing.

Model Comparison of Dark Energy models Using Deep Network

no code implementations1 Jul 2019 Shi-Yu Li, Yun-Long Li, Tong-Jie Zhang

This work uses a combination of a variational auto-encoder and generative adversarial network to compare different dark energy models in light of observations, e. g., the distance modulus from type Ia supernovae.
