Abstract

The well known ASCA observation of the relativistic iron line profile in the Seyfert 1 galaxy MGC-6-30-15 spectrum has prompted a wealth of work in modelling line profiles of both static and spinning black holes under different physical and geometrical assumptions. Not much attention, however, has been paid on the effects on the reflection continuum, which is produced along with the iron line. We present calculations of the relativistic effects on both the reflection continuum and on the line profile, obtained with a fully relativistic code in Kerr metric, and discuss the observability of these effects by present and future detectors.
