virial bh mass
Virial BH Mass:

I. Reverberation Mapping (RM)

II. Single-Epoch (SE) Methods

conclusion
Conclusion
  • The virial assumption is found valid for H
  • MgII and CIV do not show a virial behavior.
  • Separation cuts do not change much.
  • MgII not showing virial behavior:
  • A luminosity effect ==> rule out
  • The BLRs of MgII and CIV may be different from that of H
  • For C IV, has better virial-like behavior with iron-template subtraction
  • varies a lot depending on measuring ranges.
