Unveiling Active Galactic Nuclei Cores: Measuring Black Hole Masses and Emission Region Sizes with Reverberation Mapping Across Cosmic Distances

The central regions of Active Galactic Nuclei are so compact that they remain unresolved by any existing imaging techniques. However, flux variability in Active Galaxies provides a powerful means to probe these regions and, through reverberation mapping, enables us to estimate the mass of the central supermassive black hole. Reverberation mapping involves measuring the time delay between changes in the continuum emission from the accretion disk and the corresponding response from the line-emitting gas and the reprocessed torus emission. In this talk, I will discuss the use of both spectroscopic and continuum reverberation mapping to estimate central black hole masses over a range of redshifts and to constrain the sizes of key emitting regions, including the accretion disk, the emission line region, and the dusty torus surrounding the central black hole.
