Title Uncovering the mechanism behind quasi-periodic oscillations in black holes


DOI https://doi.org/10.5270/esa-f4vxdxq
Author Dr Adam Ingram
Description 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.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
