Effective equation of state in modified gravity and observational constraints

Simran Arora, Xin-he Meng, S. K. J. Pacif +1

In this article, the bulk viscosity is introduced in a modified gravity model. The gravitational action has a general form, where and are the curvature scalar an…

gravity models with observational constraints

Simran Arora, S. K. J. Pacif, Snehasish Bhattacharjee +1

The paper presents late time cosmology in gravity where the dark energy is purely geometric in nature. We start by employing a well motivated gravity model, $f(Q,…

An Accelerating Cosmological Model from a Parametrization of Hubble Parameter

S. K. J. Pacif, Md Salahuddin Khan, L. K. Paikroy +1

In view of late-time cosmic acceleration, a dark energy cosmological model is revisited wherein Einstein's cosmological constant is considered as a candidate of dark energy. Exact…

Viability of the cosmology

P. H. R. S. Moraes, P. K. Sahoo, S. K. J. Pacif

We propose a new theoretical approach for a cosmological model, which starts from an exponential of the trace of the energy-momentum tensor-dependence on the gravitational action,…

Dynamics of Bianchi Universe with Bulk Viscous Fluid in Modified Gravity

B. Mishra, S Tarai, S. K. J. Pacif

In this paper, the dynamical behavior of the anisotropic universe has been investigated in theory of gravity. The functional has been rescaled in the form $f(R,T)…

Cosmological parametrizations and their scalar field descendents

S. K. J. Pacif, K. Myrzakulov, R. Myrzakulov

We reconstruct the field potentials in case of (non)phantom fields for different models resulting from parametrization of q(t), a(t) or H(t). In addition we carry out similar proce…
