Perturbations of Spinning Black Holes beyond General Relativity: Modified Teukolsky Equation
Physical Review X, 2023 The detection of gravitational waves from compact binary mergers by the LIGO/Virgo Collaboration has, for the first time, allowed for tests of relativistic gravity in the strong, dynamical, and nonlinear regime.

New modified mimetic gravity [PDF]
International Journal of Geometric Methods in Modern Physics, 2014 A modified Mimetic gravity (MMG) is proposed as a generalization of general relativity. The model contains a physical metric which is the function of an auxiliary (unphysical) metric and a Lyra's metric. We construct different kinds of conformally invariant models in different levels of the expansion parameter λ. This model phenomenologically has been

Asymptotically flat vacuum solution for a rotating black hole in a modified gravity theory
European Physical Journal C: Particles and Fields, 2022 The theory of f(R)-gravity is one of the theories of modified Einstein gravity. The vacuum solution, on the other hand, of the field equation is the solution for black hole geometry.

Early modified gravity: Implications for cosmology [PDF]
Physical Review D, 2014 We study the effects of modifications of gravity after Big Bang Nucleosynthesis (BBN) which would manifest themselves mainly before recombination. We consider their effects on the Cosmic Microwave Background (CMB) radiation and on the formation of large scale structure.

Modeling Human Perception of Orientation in Altered Gravity
Frontiers in Systems Neuroscience, 2015 Altered gravity environments, such as those experienced by astronauts, impact spatial orientation perception and can lead to spatial disorientation and sensorimotor impairment.

HOLOGRAPHIC MODIFIED GRAVITY [PDF]
International Journal of Modern Physics D, 2008 In this paper, we investigate cosmological application of holographic dark energy density in the modified gravity framework. We employ the holographic model of dark energy to obtain the equation of state for the holographic energy density in a spatially flat universe. Our calculation shows that, taking ΩΛ = 0.73 for the present time, it is possible to
