The detection of gravitational waves from compact binary mergers by the LIGO/Virgo collaboration has, for first time, allowed tests relativistic gravity in strong, dynamical and nonlinear regime. Outside Einstein's relativity, spinning black holes may be different their general counterparts, merger then lead to a modified ringdown. We study latter and, derive Teukolsky equation, i.e., set linea...

In this letter, we introduce two new forms of uncertainty relations by extending the usual Heisenberg algebra with higher terms. Within these scenarios, at first, study on Unruh temperature. We find that temperature increases in one while it decreases other form. Next, explore thermodynamic properties a Schwarzschild black hole relying relation. present modifications mass-temperature, specific ...

A bstract The classical Raychaudhuri equation predicts the formation of conjugate points for a congruence geodesics, in finite proper time. This conjunction with Hawking-Penrose singularity theorems incompleteness geodesics and thereby singular nature practically all spacetimes. We compute generic corrections to interior Schwarzschild black hole, arising from modifications algebra inspired by g...

We extend a recently developed numerical code to obtain stationary, axisymmetric solutions that describe rotating black hole spacetimes in wide class of modified theories gravity. The utilizes relaxed Newton-Raphson method solve the full nonlinear Einstein's equations on two-dimensional grid with Newton polynomial finite difference scheme. validate this by considering static and holes general r...
