Accretion disks in Schwarzschild-MOG and Kerr-MOG backgrounds: MOG parameter in terms of observational quantities

Abstract We apply a general relativistic framework to static and rotating black hole solutions in Scalar–Tensor–Vector Gravity or modified gravity (MOG). Our results yield exact analytic, closed-form relations expressing the mass M , the MOG coupling parameter $$\alpha $$ <mml:ma...
