WebWe investigate the nonlinear evolution of black hole ringdown in the framework of higher-order metric perturbation theory. By solving the initial-value problem of a simplified nonlinear field model analytically as well… WebApr 12, 2024 · Black hole echo is an important observable that can help us better understand gravitational theories. The non-linear electrodynamic black holes can admit multi-horizon, and the destruction of outer horizons does not violate the weak cosmic censorship, which leads to the multi-peak effective potential for the scalar perturbations …
Gravitational waves from merging black holes go nonlinear
WebJan 12, 2024 · Much of the success of gravitational-wave astronomy rests on perturbation theory. Historically, perturbative analysis of gravitational-wave sources has largely focused on post-Newtonian theory. However, strong-field perturbation theory is essential in many cases such as the quasinormal ringdown following the merger of a binary system, tidally … Web78 rows · Ringdown The oscillation modes of black holes are called “quasinormal modes” (QNMs; “quasi” because they are damped by the emission of gravitational radiation). These quantities are of interest in … remote patient monitoring prevounce
