N2  - High-frequency twin peak quasiperiodic oscillations (QPOs) are observed in four microquasars, i.e., Galactic black hole binary systems, with frequency ratio very close to 3:2. In the microquasar GRS 1915+105, the structure of QPOs exhibits additional frequencies, and more than two frequencies are observed in the Galaxy nuclei Sgr A*, or in some extragalactic sources (NGC 4051, MCG-6-30-15 and NGC 5408 X-1). The observed QPOs can be explained by a variety of the orbital resonance model versions assumingresonance of oscillations with the Keplerian frequency or the vertical epicyclic frequency, and the radial epicyclic frequency, or some combinations of these frequencies. Generally, different resonances could arise at different radii of an accretion disc.
