Holographic Dark Energy Model with Interaction and Cosmological Constant in the Flat Space-Time

  • Hassan Saadat
Article

Abstract

In this paper we consider holographic dark energy model with interaction in the flat space-time with non-zero cosmological constant. We calculate cosmic scale factor and Hubble expansion parameter by using the time-dependent dark energy density. Then, we obtain phenomenological interaction between holographic dark energy and matter. We fixed our solution by using the observational data.

Keywords

Dark energy Cosmological constant Holography Cosmology
