The cosmological background and the "external field" in Modified Gravity (MOG)
J. W. Moffat, V. T. Toth
We investigate the contributions of the Friedmann-Lemaître-Robertson-Walker metric of the standard cosmology as an asymptotic boundary condition on the first-order approximation of…
Gravitoelectromagnetism and stellar orbits in galaxies
Viktor T. Toth
Beyond the Newtonian approximation, gravitational fields in general relativity can be described using a formalism known as gravitoelectromagnetism. In this formalism a vector poten…
Gravitational lensing by an extended mass distribution
Slava G. Turyshev, Viktor T. Toth
We continue our investigation of the optical properties of the solar gravitational lens (SGL). We treat the Sun as an extended axisymmetric body and model its gravitational field u…
Scalar-Tensor-Vector modified gravity in light of the Planck 2018 data
J. W. Moffat, V. T. Toth
The recent data release by the Planck satellite collaboration presents a renewed challenge for modified theories of gravitation. Such theories must be capable of reproducing the ob…
Imaging point sources with the gravitational lens of an extended Sun
Slava G. Turyshev, Viktor T. Toth
We study the optical properties of the solar gravitational lens (SGL) while treating the Sun as an extended, axisymmetric and rotating body. The gravitational field of the Sun is r…
Diffraction of electromagnetic waves by an extended gravitational lens
Slava G. Turyshev, Viktor T. Toth
We continue our study of the optical properties of the solar gravitational lens (SGL). Taking the next step beyond representing it as an idealized monopole, we now characterize the…
