Uncovering the mechanism behind quasi-periodic oscillations in black holes
Abstract
We propose a triggered 200ks XMM-Newton observation of a high inclination black hole binary in the hard intermediate state. This will allow us to constrain a characteristic shift in the iron line profile between the rising and falling phases of the quasi-periodic oscillations (QPOs) observed in these objects. Such a property is a necessary and sufficient condition of a QPO driven by precession in the inner regions of the accretion flow and is predicted by our model which invokes the relativistic effect of frame dragging. The model predicts the QPO phase dependence of the iron line to be stronger for high inclination sources displaying intermediate hardness ratios, leaving the hard intermediate state as the ideal configuration. We will trigger the observation from Swift monitoring throughout the outburst.
