Observational constraints on the massive neutrinos induced late-time cosmic acceleration
Mohit K. Sharma, Shibesh Kumar Jas Pacif, Shynaray Myrzakul +1
We study a scenario based upon a mass-less theory coupled to massive neutrino matter with symmetry using a conformal coupling, …
Cosmological aspects of gravity in a simple model with a parametrization of
Ritika Nagpal, Shibesh Kumar Jas Pacif
In this paper, we have considered a quadratic variation of the deceleration parameter () as a function of cosmic time () which describes a smooth transition from the decelera…
Bulk viscous matter and the cosmic acceleration of the universe in gravity
Simran Arora, S. K. J. Pacif, Abhishek Parida +1
We have studied bulk viscosity in the modified gravity theory formalism, where represents the non-metricity and denotes the trace of energy-momentum tensor within…
Cosmic acceleration with bulk viscosity in modified gravity
Raja Solanki, S. K. J. Pacif, Abhishek Parida +1
In this article, we have investigated the role of bulk viscosity to study the accelerated expansion of the universe in the framework of modified gravity. The gravitational a…
Late-time acceleration with a scalar field source: Observational constraints and statefinder diagnostics
S. K. J. Pacif, Simran Arora, P. K. Sahoo
This article discusses a dark energy cosmological model in the standard theory of gravity - general relativity with a broad scalar field as a source. Exact solutions of Einstein's…
