Confrontation of Observation and Theory: High Frequency QPOs in X-ray Binaries, Tidal Disruption Events, and Active Galactic Nuclei

摘要: We compile observations of high-frequency quasi-periodic oscillations (QPOs) around black holes, both stellar and supermassive, compare their positions in the parameter space hole mass, spin, oscillation frequency. find that supermassive holes occupy a separate region than stellar, further, QPOs seen tidal disruption events rather Seyfert-type AGN an entirely different space. then these results to orbital resonance, diskoseismic, warped disk, disk-jet coupling theoretical models for origin QPOs. while mass are generally consistent with above models, decidedly not. Oscillations near frequency innermost stable circular orbit (ISCO), not accounted by any physical consideration. This indicates despite scale invariance accretion processes implied decades-wide correlation between QPO theory high must relate more just spin.
