T Tangphati, M Youk, S Ponglertsakul - Journal of High Energy …, 2024 - Elsevier
We construct asymptotically flat, static spherically symmetric black holes with regular centre
in f (R, T) gravity coupled to nonlinear electrodynamics Lagrangian. We obtain generalized …

Rotating kiselev black holes in f (R, T) gravity

SG Ghosh, SU Islam, SD Maharaj - Physica Scripta, 2024 - iopscience.iop.org
Exact solutions describing rotating black holes can provide significant opportunities for
testing modified theories of gravity, which are motivated by the challenges posed by dark …

Dynamical reconstruction of the model in scalar-tensor gravity

TB Gonçalves, JL Rosa, FSN Lobo - Physical Review D, 2024 - APS
In this work, we use the dynamical system approach to explore the cosmological
background evolution of the scalar-tensor representation of f (R, T) gravity, where R is the …

Photon orbits and phase transitions in Kiselev-AdS black holes from gravity

A Sood, A Kumar, JK Singh, SG Ghosh - The European Physical Journal C, 2024 - Springer
The acceleration observed in cosmological expansion is often attributed to negative
pressure, potentially arising from quintessence. We explore the relationship between the …

Formation of stable wormhole solution with non-commutative geometry in the framework of gravity

N Loewer, M Tayde, PK Sahoo - arXiv preprint arXiv:2409.04172, 2024 - arxiv.org
This research delves into the potential existence of traversable wormholes (WHs) within the
framework of $ f (R,\mathcal {L} _m, T) $ gravity, a modification that includes the matter …

Black hole solutions surrounded by anisotropic fluid in $ f (\mathbb {T},\CMcal {T}) $ gravity

FM da Silva, LCN Santos, VB Bezerra - arXiv preprint arXiv:2405.20966, 2024 - arxiv.org
In this work, we investigate some extensions of the Kiselev black hole solutions in the
context of $ f (\mathbb {T},\CMcal {T}) $ gravity. By mapping the components of the Kiselev …

Wormholes in gravity with variable equation of state

S Rastgoo, F Parsaei - arXiv preprint arXiv:2408.04402, 2024 - arxiv.org
In this work, we introduce a novel set of asymptotically flat wormhole solutions within the
framework of $ f (R, T) $ theory of gravity. Considering a linear $ f (R, T)= R+ 2\lambda T …
