ABSTRACT | |
X-ray reverberation shows that the corona is compact, within 10 gravitational radii of the central black hole, and irradiates a disc that extends down to or near the ISCO. However, these results appear in tension with recent Swift disc reverberation results, where the time delay between X-rays and UV/optical is much larger than expected from the standard reprocessing model in which a compact corona irradiates and thermalizes a thin accretion disc. In order to explain these disc reverberation results, two suggestions have been made: either (1) the thin disc is truncated with a hot inner flow or (2) absorption and scattering from the broad line region affect the time lag measurements. Neither of these two scenarios can be properly tested with Swift alone. We require XMM-Newton to study the p |
