The cold dark-matter model successfully explains both the emergence and evolution of
cosmic structures on large scales and, when we include a cosmological constant, the …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We study the strong gravitational lensing effect around rotating black holes in different
gravity theories. By calculating the deflection angle of strong gravitational lensing, we …

We study the influence of parameter α on the optical features of Schwarzschild-MOG black
holes with different thin accretions in scalar-tensor-vector gravity. As α increases from 0, the …

The field equations for scalar–tensor–vector gravity (STVG) or modified gravity (MOG) have
a static, spherically symmetric black hole solution determined by the mass MM with two …

We have obtained the first constraint of the parameter space of Scalar–Tensor–Vector
Gravity using the motion of the S2-star around the supermassive black hole at the centre of …

The shadows cast by non-rotating and rotating modified gravity black holes are determined
by the two parameters mass MM and angular momentum J= Ma J= M a. The sizes of the …

We investigate the shadow cast by a regular black hole in scalar-tensor-vector modified
gravity theory. This black hole differs from a Schwarzschild-Kerr black hole by the …

The paper has explored analogue of gravitational synchrotron massive particle and Penrose
process in MOdified Gravity (MOG) known as Scalar-Tensor-Vector-Gravity (STVG) …

Galaxy rotation curves determined observationally out to a radius well beyond the galaxy
cores can provide a critical test of modified gravity models without dark matter. The predicted …
