The Integrated Sachs-Wolfe Effect in Interacting Dark Matter-Dark Energy Models

Understand

Interacting dark matter-dark energy (IDMDE) models can be taken to account as one of the present challenges that may affect the cosmic structures.

• In this work, we study the integrated Sachs-Wolfe (ISW) effect in IDMDE models.
• To this end, we initially introduce a theoretical framework for IDMDE models.
• Moreover, we briefly discuss the stability conditions of IDMDE models and by specifying a simple functional form for the energy density transfer rate, we calculate the perturbation equations.
