Traversable wormhole models in gravity
B. Mishra, A. S. Agrawal, S. K. Tripathy +1
In this work, we analyze the wormhole solutions in gravity. Specifically we sought for wormhole geometry solutions for the following three shape functions: (i) $b(r)=r_{0}+ρ…
Cosmological model with time varying deceleration parameter in gravity
Santosh V. Lohakare, S. K. Tripathy, B. Mishra
In this paper, we study the dynamical behaviour of the Universe in the theory of gravity, where and respectively denote the Ricci scalar and Gauss-Bonnet invariant…
Electromagnetic neural source imaging under sparsity constraints with SURE-based hyperparameter tuning
Pierre-Antoine Bannier, Quentin Bertrand, Joseph Salmon +1
Estimators based on non-convex sparsity-promoting penalties were shown to yield state-of-the-art solutions to the magneto-/electroencephalography (M/EEG) brain source localization…
f(R) wormholes embedded in a pseudo--Euclidean space
A. S. Agrawal, B. Mishra, Francisco Tello-Ortiz +1
This work is devoted to the study of analytic wormhole solutions within the framework of gravity theory. To check the possibility of having wormhole structures satisfying en…
Bouncing cosmology in extended gravity and its reconstruction as dark energy model
A. S. Agrawal, Francisco Tello-Ortiz, B. Mishra +1
In this paper, we have presented a bouncing cosmological model of the Universe in an extended theory of gravity. The dynamical behaviour of the model obtained from the flat FLRW sp…
Matter Bounce Scenario and the Dynamical aspects in f(Q,T) Gravity
A. S. Agrawal, Laxmipriya Pati, S. K. Tripathy +1
In the context of the late time cosmic acceleration phenomenon, many geometrically modified theories of gravity have been proposed in recent times. In this paper, we have investiga…
Model parameters in the context of late time cosmic acceleration in gravity
Laxmipriya Pati, B. Mishra, S. K. Tripathy
The dynamical aspects of some accelerating models are investigated in the framework of an extension of symmetric teleparllel gravity dubbed as f(Q,T) gravity. In this gravity theor…
Cosmological models with Big rip and Pseudo rip Scenarios in extended theory of gravity
Pratik P. Ray, Sankarsan Tarai, B. Mishra +1
In this paper, we have presented the big rip and pseudo rip cosmological models in an extended theory of gravity. The matter field is considered to be that of perfect fluid. The ge…
Cosmological models with a Hybrid Scale Factor
S. K. Tripathy, B. Mishra, Maxim Khlopov +1
In this brief review, we present some cosmological models with a Hybrid Scale Factor (HSF) in the framework of general relativity (GR). The hybrid scale factor fosters an early dec…
Wormhole solutions in Gravity
B. Mishra, A. S. Agrawal, S. K. Tripathy. Saibal. Ray
In this work, we have studied the traversable wormholes geometry in theory gravity, where be the Ricci scalar. The wormhole solution for some assumed functions ha…
Stability analysis of two-fluid dark energy models
B. Mishra, Fakhereh Md. Esmaeili, Pratik P. Ray +1
In this paper, we have studied the stability of the cosmological models with dark energy and combination of matter fields and dark energy in an anisotropic space time. The pressure…
Cosmology from non-minimal geometry-matter coupling
B. S. Gonçalves, P. H. R. S. Moraes, B. Mishra
We construct a cosmological model from the inception of the Friedmann-Lemâitre-Robertson-Walker metric into the field equations of the f(R,L_m) gravity theory, with R being the Ric…
