Equatorial periodic orbits and gravitational waveforms in Bardeen black holes surrounded by perfect fluid dark matter
Sohan Kumar Jha
To probe the interplay between dark matter (DM) and non-linear electrodynamics (NED), we consider the Bardeen black hole (BH) surrounded by perfect fluid dark matter (PFDM). We fir…
Strong gravitational lensing and Quasiperiodic oscillations as a probe for an electrically charged Lorentz symmetry-violating black hole
Sohan Kumar Jha
This study examines the combined effect of electric charge and Lorentz symmetry breaking (LSB) on the observables of strong gravitational lensing (SGL) and the dynamics of quasiper…
Probing a NED inspired Magnetically Charged Black Hole in the Hernquist Dark Matter Halo
Sohan Kumar Jha
With an intent to examine the combined effect of non-linear electrodynamics (NED) and dark matter (DM), we obtain a static and spherically symmetric solution with the black hole (B…
Black hole surrounded by perfect fluid dark matter with a background Kalb-Ramond field
Sohan Kumar Jha
With an intent to explore the interplay between the Lorentz symmetry breaking (LSB) and the presence of dark matter (DM), we obtain a static and spherically symmetric black hole (B…
Non-Minimal RT Coupling and its Impact on Inflationary Evolution in f(R, T) Gravity
Sohan Kumar Jha, Anisur Rahaman
We examine inflationary models in the gravity framework where we have a conformal constant and an -mixing term apart from an R term. The RT-mixing term introduces non…
Thermodynamics, Weak Gravitational Lensing, and Parameter Estimation of a Schwarzschild Black Hole Immersed in Hernquist Dark Matter Halo
Sohan Kumar Jha
In this article, we obtain a novel black hole (BH) solution of a Schwarzschild BH immersed in a Hernquist dark matter (SBHD) halo. The thermodynamic properties of the resultant spa…
