The MBH - σ* relationship for AGNs
The MBH - σ* relationship for AGNs. Filled squares represent AGNs with velocity dispersion measurements based on the Ca II triplet. The open star at the top represents the Watson et al. measurement for PG 1426+015, while the open square to its immediate left is the position of PG 1426+015 in a previous study. The superior spectrum obtained using NIFS and Altair led to a more precise measurement of the velocity dispersion.
