Observational constraints in late time for an axially symmetric transitioning model with bulk viscous fluid
G. K. Goswami, Anirudh Pradhan, Vipin Chandra Dubey
In this paper, we explore an axially symmetric Bianchi type-I model of the universe with bulk viscous fluid as a source of gravitational field under the framework of Einstein's fie…
