Transitioning universe with hybrid scalar field in Bianchi I space-time

In this paper we investigate a Bianchi type I transitioning Universe in Brans-Dicke theory. To get an explicit solution of the field equations, we assume scalar field as phi = phi(0) [t(alpha)exp(beta t)](delta) with phi(0), alpha, beta and d as constants. The values of alpha and beta are obtained by probing the proposed model with recent observational Hubble data (OHD) points. The interacting and non-interacting scenarios between dark matter and dark energy of the derived Universe within the framework of Brans-Dicke gravity are investigated. The om(z) analysis of the Universe in derived model shows that the Universe is filled with dynamical dark energy with its equation of state parameter omega(de) > -1. Hence the Universe behaves like a quintessence model at present epoch. Some physical properties of the Universe are also discussed. (C) 2020 Elsevier B.V. All rights reserved.
