An Abel-Inversion Formalism for Spacetime Metric Reconstruction from Light Deflection
Aniruddha Ghosh, Ujjal Debnath
We develop an inverse lensing formalism for reconstructing the metric function of a static, spherically symmetric spacetime directly from the gravitational deflection angle of ligh…

The New Black Hole Solution with Anisotropic Fluid in f(R,Lm, T) Gravity: Thermodynamics
Aniruddha Ghosh, Ujjal Debnath
In this work, we derive a new class of analytic black hole solutions within the framework of f(R,Lm, T) gravity, where the black hole is surrounded by an anisotropic fluid acting a…

New Black Hole Solutions in f(P) Gravity and their Thermodynamic Nature
Aniruddha Ghosh, Ujjal Debnath
Black holes are the fascinating objects in the universe. They represent extreme deformations in spacetime geometry. Here, we construct f(P) gravity and the first example of static-…
