Supermassive BH with high accretion rates. XV. MgII
Listed in IVOA Registry (Virtual Observatory)
As the 15th paper in a series reporting on a large reverberation mapping (RM) campaign of super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs), we present the results of measurements of the MgII lines in 18 SEAMBHs monitored spectroscopically from 2017 to 2024.
Description
Among these, the time lags of MgII have been successfully determined for eight of the 18 objects, thereby expanding the current Mg ii RM sample, particularly at higher accretion rates.
By incorporating measurements of the line widths, we determine the masses of their central supermassive black holes. Based on these new measurements, we update the relation between the MgII radius and the monochromatic luminosity at 3000{AA} (R_MgII_-L_3000_ relation), yielding a slope of 0.24{\pm}0.03, which is slightly shallower than, yet still consistent with, previously reported values. Similar to the H{beta} lines, the Mg ii time lags in SEAMBHs are shorter than those of AGNs with normal accretion rates at comparable luminosities.

The deviation of AGNs from the best-fit R_MgII_-L_3000_ relation shows a strong correlation with the accretion rate, while no significant correlation is found between the deviation and the flux ratio of UV iron to MgII.
