Testing the Interaction Between Baryons and Dark Energy with Recent Cosmological Observations

Zhang, Jia; Cao, Shuo; Chen, Yun +1 more

We study a modified interacting dark energy (MIDE) model as a candidate to describe possible interaction between dark energy and dark matter as well as that between dark energy and baryonic matter. More specifically, we introduce a new parameter γ _b to quantify the extent of interaction between dark energy and baryons. With three clas…
