Slowly rotating black hole
Webb14 feb. 2014 · Astronomers have actually detected supermassive black holes spinning at the limits predicted by these theories. One black hole, at the heart of galaxy NGC 1365 is turning at 84% the speed of light ... The Kerr geometry is often used as a model of a rotating black hole but if the solution is held to be valid only outside some compact region (subject to certain restrictions), in principle, it should be able to be used as an exterior solution to model the gravitational field around a rotating massive object other than a black hole such as a neutron star, or the Earth. This works out very nicely for the non-rotating case, where the Schwarzschild vacuum exterior can be matched to a Schwarzsc…

According to the theory of general relativity, this phenomenon is due to the … Webb10 apr. 2024 · Recent work has demonstrated that rotating black holes in dynamical Chern-Simons gravity possess unique structures, the “Chern-Simons caps,” which may influence the behavior of matter near the black hole. Motivated by the presence of these caps, we study superradiance in dynamical Chern-Simons gravity in the context of a slowly …
WebbThe set of solutions we obtain is compatible with asymptotically flat geometries exhibiting a regular event horizon at which the dilaton is well-behaved. For the 4-dimensional case, we also derive the stationary black hole configuration at first order in α ′ and in the slowly rotating approximation.
