Numerical stability of the electromagnetic quasinormal and quasibound modes of Kerr black holes
Denitsa Staicova, Plamen Fiziev
The proper understanding of the electromagnetic counterpart of gravity-waves emitters is of serious interest to the multimessenger astronomy. In this article, we study the numerica…
New results for electromagnetic quasinormal and quasibound modes of Kerr black holes
Denitsa Staicova, Plamen Fiziev
The perturbations of the Kerr metric and the miracle of their exact solutions play a critical role in the comparison of predictions of general relativity with astrophysical observa…
New results for electromagnetic quasinormal modes of black holes
Denitsa Staicova, Plamen Fiziev
The differential equations governing the late-time ring-down of the perturbations of the Kerr metric, the Teukolsky Angular Equation and the Teukolsky Radial Equation, can be solve…
The Spectrum of Electromagnetic Jets from Kerr Black Holes and Naked Singularities in the Teukolsky Perturbation Theory
Denitsa R. Staicova, Plamen P. Fiziev
We give a new theoretical basis for examination of the presence of the Kerr black hole (KBH) or the Kerr naked singularity (KNS) in the central engine of different astrophysical ob…
A new model of the Central Engine of GRB and the Cosmic Jets
Plamen P. Fiziev, Denitsa R. Staicova
Despite all the already existing observational data, current models still cannot explain completely the excessive energy output and the time variability of GRB. One of the reasons…
