Reverberation mapping (RM) is the leading technique used to measure direct black hole masses in active galactic nuclei (AGN) outside of the local Universe. The strength of RM lies in its ability to resolve the innermost regions of AGN in the time-domain, rather than spatially, allowing us to study these compact cores out to high redshifts. Additionally, reverberation measurements calibrate secondary mass-scaling relations used to estimate single-epoch virial black hole masses. However, the RM technique is observationally intensive and consequently few measurements have been made, particularly at z>0.3. The Australian Dark Energy Survey (OzDES) RM Program leveraged high-multiplexed spectroscopy to monitor over 700 AGN up to z~4, probing new regions of the AGN luminosity-redshift parameter space. In this thesis, I deliver results from the OzDES RM Program and explore the complexities of performing reverberation mapping on this `industrial-scale’. |
