In this paper we propose a way of determining the subleading corrections to the BekensteinHawking black hole entropy by considering a modified generalized uncertainty principle with two parameters. In the context of modified generalized uncertainty principle, coefficients of the correction terms of black hole entropy are written in terms of combination of the parameters. We also calculate corre...

A covariant modified gravity (MOG) is formulated by adding to general relativity two new degrees of freedom, a scalar field gravitational coupling strength G = 1/χ and spin 1 vector ϕμ. The written as GN(1+α) where GN Newton's constant, the source charge for Qg √α GNM, M mass body. Cosmological solutions theory are derived in homogeneous isotropic cosmology. Black holes MOG stationary end produ...

We study the black hole's shadow for Schwarzschild - de Sitter and Kerr metrics with contribution of cosmological constant \Lambda. Based on reported parameters M87* hole we obtain constraints $\Lambda$ show agreement data. It is shown that, coupling \Lambda-term spin parameter reveals peculiarities photon spheres hence shadows. Within parametrized post-Newtonian formalism constraint correspond...
