Perturbed Kerr Black Holes can probe deviations from General Relativity
Enrico Barausse, Thomas P. Sotiriou
Although the Kerr solution is common to many gravity theories, its perturbations are different in different theories. Hence, perturbed Kerr black holes can probe deviations from Ge…

Polytropic spheres in Palatini f(R) gravity
Enrico Barausse, Thomas P. Sotiriou, John C. Miller
We examine static spherically symmetric polytropic spheres in Palatini f(R) gravity and show that no regular solutions to the field equations exist for physically relevant cases su…
