Title Testing Black Hole Unification


DOI 10.5270/esa-2tqe4bd
Author Dr Simon Vaughan
Description We propose a 480 ks observation of NGC 4051 to definitively test for quasi-periodic oscillations (QPOs) analogous to those seen in Galactic Black Holes (GBHs). These would confirm the unifying link between accreting black holes of all masses and provide a powerful new diagnostic of the strong-gravity region, giving the most model-independent constraints on black hole spin. We will reveal for the first time the X-ray variability of a black hole at frequencies far above the Keplerian frequency of the innermost stable circular orbit, beyond what is possible for GBHs, and use this to probe the dynamics and geometry of the X-ray emission region.

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.
