ABSTRACT
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.
