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…
On the final spin from the coalescence of two black holes
Luciano Rezzolla, Enrico Barausse, Ernst Nils Dorband +4
We provide a compact analytic formula to compute the spin of the black hole produced by the coalescence of two black holes. The expression, which uses an analytic fit of numerical-…
Curvature singularities, tidal forces and the viability of Palatini f(R) gravity
E. Barausse, T. P. Sotiriou, J. C. Miller
In a previous paper we showed that static spherically symmetric objects which, in the vicinity of their surface, are well-described by a polytropic equation of state with 3/2<Gamma…
Relativistic dynamical friction in a collisional fluid
Enrico Barausse
The dynamical friction force experienced by a body moving at relativistic speed in a gaseous medium is examined. This force, which arises due to the gravitational interaction of th…
Circular and non-circular nearly horizon-skimming orbits in Kerr spacetimes
Enrico Barausse, Scott A. Hughes, Luciano Rezzolla
We have performed a detailed analysis of orbital motion in the vicinity of a nearly extremal Kerr black hole. For very rapidly rotating black holes (spin a=J/M>0.9524M) we have fou…
A no-go theorem for polytropic spheres in Palatini f(R) gravity
Enrico Barausse, Thomas P. Sotiriou, John C. Miller
Non-vacuum static spherically-symmetric solutions in Palatini f(R) gravity are examined. It is shown that for generic choices of f(R), there are commonly-used equations of state fo…
