III. Interacting Dark Energy: Summary of Models, Pathologies, and Constraints
Marcel van der Westhuizen, Amare Abebe, Eleonora Di Valentino
We present an overview of the main results from our two companion papers that are relevant for observational constraints on interacting dark energy (IDE) models. We provide analyti…
I. Linear Interacting Dark Energy: Analytical Solutions and Theoretical Pathologies
Marcel van der Westhuizen, Amare Abebe, Eleonora Di Valentino
Interacting dark energy (IDE) models, in which dark matter (DM) and dark energy (DE) exchange energy through a non-gravitational interaction, have long been proposed as candidates…
II. Non-Linear Interacting Dark Energy: Analytical Solutions and Theoretical Pathologies
Marcel van der Westhuizen, Amare Abebe, Eleonora Di Valentino
We investigate interacting dark energy (IDE) models with phenomenological, non-linear interaction kernels , specifically $Q_{1}=3Hδ\left(\frac{ρ_{\rm dm}ρ_{\rm de}}{ρ_{\rm dm}+ρ…
