A smooth BTZ black bounce with an extremal null throat
Farzad Milani
We study a static, circularly symmetric deformation of the non-rotating BTZ black hole obtained by inserting a smooth transition function into the \emph{inverse} radial metric comp…
Smooth Signature Change as a Mechanism for Singularity Avoidance in BTZ Black Holes
Farzad Milani
Spacetime singularities represent a fundamental challenge in classical general relativity, prompting investigations into mechanisms that could resolve or avoid them. The paradigm o…
Gravitational Wave Backreaction in Gravity
Farzad Milani
We develop a complete framework for gravitational wave propagation and backreaction in modified gravity. Using a scalar-tensor formulation with two auxiliary fields, we de…
Non-singular Bouncing Cosmology in --Quintom model
Farzad Milani
We present a unified framework for non-singular bouncing cosmologies in modified gravity, combining geometry with quintom scalar dynamics in a flat FLRW universe. While…
Bouncing Theory in the Modified Gravity
Farzad Milani
In this study, we explore the dynamics of the universe using a modified gravity model represented by , where is the Ricci scalar, is the Gauss-Bonnet invariant,…
