Virial bh mass
Virial BH Mass:

I. Reverberation Mapping (RM)

II. Single-Epoch (SE) Methods



Mg ii correlation
Mg II - correlation


C iv correlation
C IV - correlation


Mg ii subset having h
Mg II subset(having H)





C iv more test

I. With narrow -line subtraction

C IV more test


II. With iron-template subtraction

C IV more test


III. With narrow -line and iron-template subtractions

C IV more test






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.
