| Abstract: | The most luminous persistent objects in the Universe are accreting supermassive black holes, known as quasars. Our 1989 paper on relativistic reflection showed how X-ray emission lines from the accretion disc appear broad and skew to the distant observer due to gravitational redshift and the Doppler effect. We also noted that time lags - reverberation - should also be detected. Reflection was seen with Ginga, the relativistic broad iron line in 1995 with ASCA and reverberation in 2009 with XMM. X-ray observations of relativistic reflection and reverberation have now become commonplace. After briefly reviewing the history, I will concentrate on recent work which has enabled the geometry of the inner disk and corona to be mapped, so revealing how quasars work. |
