- Аннотация: The first set of supermassive black hole mass estimates, published from 1977 to 1984 by E.A. Dibai, are shown to be in excellent agreement with recent reverberation-mapping estimates. Comparison of the masses of 17 AGNs covering a mass range from about 10$^6$ to 10$^9$ M $_&sun;$ shows that the Dibai mass estimates agree with reverberation-mapping mass estimates to significantly better than \plusmn0.3 dex and were, on average, only 0.14 dex (\tilde40%) systematically lower than masses obtained from reverberation mapping. This surprising agreement with the results of over a quarter of a century ago has important implication for the structure and kinematics of AGNs and implies that type-1 AGNs are very similar. Our results give strong support to the use of the single-epoch-spectrum (Dibai) method for investigating the co-evolution of supermassive black holes and their host galaxies.
