AGN Continuum Reverberation Mapping

Abstract:

Reverberation mapping (RM) is a powerful tool to explore the unresolved central region of active galactic nucleus (AGN), e.g., accretion disk. Determining the structure of accretion disks in AGN is fundamental to understanding the growth of supermassive black holes, confirming the standard thin disk theory, and examining the X-ray reprocessing variability model. However, recent continuum RM suggests that the observed accretion disk size is around three times larger than prediction. In this talk, I will introduce a new component, i.e., diffuse continuum, to explain the discrepancy between observations and theorical predictions.
