Revisiting the cosmological constraints on the interacting dark energy models
چکیده انگلیسی
In this work, we consider the cosmological constraints on the interacting dark energy models. We generalize the models considered previously by Guo et al. (2007) [1], Costa and Alcaniz (2010) [2], and try to discuss two general types of models: type I models are characterized by ρX/ρm=f(a) and f(a) can be any function of scale factor a, whereas type II models are characterized by ρm=ρm0a−3+ϵ(a) and ϵ(a) can be any function of a. We obtain the cosmological constraints on the type I and II models with power-law, CPL-like, logarithmic f(a) and ϵ(a) by using the latest observational data.
