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…
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…
