Black-hole potential field
WebApr 10, 2024 · Black hole superradiance provides a window into the dynamics of light scalar fields and their interactions close to a rotating black hole. Owing to the rotation of the black hole, the amplitude of the scalar field becomes magnified, leading to a ``black hole bomb'' effect. Recent work has demonstrated that rotating black holes in dynamical … WebCharged black holes are two of four possible types of black holes that have been found by solving Einstein's theory of gravitation, general relativity. The mathematical solutions for the shape of space and the electric and magnetic fields near a black hole are named after the persons who first worked them out.

WebFeb 7, 2024 · The black hole essentially donates some of its angular momentum to this mass, thereby increasing its energy. A recent suggestion is that energy could be harnessed from this process by breaking and recombining magnetic field lines in the ergosphere. WebSep 8, 2024 · The mass of the black hole is defined exactly and only as the apparent Newtonian mass M in the ≈ − M / r 2 gravitational force these observers at infinity feel. In other words, you could understand the mass more as total gravitating energy as felt by observers at infinity.
WebWe investigate the amplification of curvature perturbations in a two-field inflation model featuring a Gaussian potential bump. When the inflaton encounters a potential bump along the inflationary trajectory, its rolling speed is generally reduced, potentially causing a violation of the slow-roll condition. Consequently, the original decaying modes of … WebJul 10, 2024 · This telescope is ideal for the task owing to its exceptionally large field of view.

WebSep 27, 2016 · 7. The “Core” of a Blazar Jet. For various reasons, there has been considerable confusion with the blazar community over the so-called “core” seen on VLBI images. Some automatically associate it with the central engine, thinking that the core is the base of the jet, in the immediate environs of the black hole. WebAn exact solution to the Einstein field equations is the Schwarzschild metric, which corresponds to the external gravitational field of an uncharged, non-rotating, spherically symmetric body of mass .The Schwarzschild solution can be written as = where , in the case of a test particle of small positive mass, is the proper time (time measured by a …
