N2  - A recent measurement of double peak QPOs frequencies in Sgr A is consistent with the 3:2 ratio. The same ratio is firmly established by previous observations in all double peak kHz QPOs in microquasars and theoretically explained by orbital epicyclic resonances excited in nearly Keplerian accretion flow in black holes strong gravity. If confirmed, the 3:2 ratio of double peak QPOs in Sgr A will be of a fundamental importance for the black hole accretion theory, by providing another clear argument that the accretion disk oscillations are indeed governed by non-linear, strong-gravity physics.
