Model for Modified Holographic Ricci Dark Energy in Gravitation Theory of Branc Dicke

Abstract

In this cosmological model, we have studied the spatially homogeneous and anisotropic Bianchi type and axially symmetric models filled with dark matter and dark energy in the presence of the Brans-Dicke and carl Hranc [1] theory of gravitation. Here, we consider the modified holographic Ricci dark energy dened by Chen and Jing [2] as a suitable condition of dark energy. To obtain a solution we assumed the scale factor a(t) = [sinh(gamma t)]^(1/p) used Mishra et. al.[3]. We have solved eld equations of Brans-Dicke theory of gravitation with the help of an axially symmetric anisotropic Bianchi-type space-time. We have determined the cosmological parameters, namely, EoS parameter, MHRDE density matter density, skewness parameter, and BD scalar eld. Here the various phenomena like the Big Bang, expanding the universe, and shift from anisotropy to isotropy are observed in the model. A detailed physical discussion of these dynamical parameters is presented through graphically. Some physical and geometrical behaviors of the models are also discussed and found to be in good agreement with the recent observations (OHD+JLA) datasets.
