What broad emission lines tell us about how active galactic nuclei work

CM Gaskell - New Astronomy Reviews, 2009 - Elsevier
I review progress made in understanding the nature of the broad-line region (BLR) of active
galactic nuclei (AGNs) and the role BLRs play in the AGN phenomenon. The high equivalent …
