Abstract We give a new theoretical basis for examination of the presence of Kerr black hole (KBH) or Kerr naked singularity (KNS) in the central engine of different astrophysical objects like X-ray binary systems, gamma ray bursts (GRBs), active galactic nuclei (AGN), etc. Our method is based on the study of spectra of the relativistic jets, typically formed around these objects. Such theoretical spectra are calculated numerically for the first time. Our main result is a detailed description of the qualitative change of behavior of electromagnetic jet frequencies under the transition from KBH to KNS, considered here as a bifurcation of Kerr metric. We show that quite surprisingly our novel electromagnetic jet spectra describe a linearly stable electromagnetic jets both from KBH and KNS. Numerical investigation of the dependence of these jet spectra on the rotation of Kerr metric is presented and discussed. It is based on the study of corresponding exact solutions of the Teukolsky master equation for electromagnetic perturbations of Kerr metric.
