The non-Kerr black hole with acceleration

Usman A. Gillani, Rehana Rahim, Khalid Saifullah

The no-hair theorem can be tested in the strong gravity regime by using the top-bottom approach and the bottom-top approach. The non-Kerr spacetime of the later approach is an idea…

Linear cosmological perturbations in almost scale-invariant fourth-order gravity

Jorge L. Fuentes, Usman A. Gillani, Karim A. Malik

We study a class of almost scale-invariant modified gravity theories, using a particular form of $f (R, G) = α R^{2} + β G lo g G$ where $R$ and $G$ are the Ricci and Gauss-Bonnet scala…
