Quintessence phase of the late-time Universe in gravity
Shambel Sahlu, Bhupendra Kumar Shukla, Rishi Kumar Tiwari +2
In this paper, we have studied the late-time accelerating expansion of the Universe using the matter-geometry coupled gravity model, where is the non-metricity sc…
A cosmological model with time dependent , and viscous fluid in General Relativity
Rishi Kumar Tiwari, Alnadhief H. A. Alfedeel, Değer Sofuoğlu +2
In this paper, we investigate Bianchi type cosmological models with bulk viscous fluid and time varying cosmological and Newtonian parameters. The Einstein's field equa…
Noncommutative geometry inspired 3-dimensional charged black hole solution in an anti-de Sitter background space-time
Farook Rahaman, Piyali Bhar, Ranjan Sharma +1
We report a 3D charged black hole solution in an anti desetter space inspired by noncommutative geometry.In this construction,the black hole exhibits two horizon which turn into a…
Polytropic bulk viscous cosmological model with variable G and Λ
Rishi Kumar Tiwari, Mukesh Sharma, Sonia Sharma
We consider a Bianchi type-I Polytropic bulk viscous fluid cosmological model with variable G and Λ. To get a deterministic model, we assume some conditions of A, B, C, and polytro…
Five Dimensional Cosmological Models in General Relativity
R. K. Tiwari, Farook Rahaman, Saibal Ray
A Five dimensional Kaluza-Klein space-time is considered in the presence of a perfect fluid source with variable G and . An expanding universe is found by using a relation betwe…
