Estimating Black Hole Masses in Active Galaxies Using the Halpha Emission Line

1 code implementation15 Aug 2005 Jenny E. Greene, Luis C. Ho

It has been established that virial masses for black holes in low-redshift active galaxies can be estimated from measurements of the optical continuum strength and the width of the broad Hbeta line.
