| Abstract: |
From the spectral monitoring of 3C390.3 in 1995-1999 we have obtained that the H-beta blue bump radial velocity variations follow the same trend found by Eracleous et al.(1997). Their model for a binary BH with a very large mass (> 1011 solar mass) seems to fit our data as well. Hence, our results provide further support to the rejection of the massive binary BH hypothesis for 3C 390.3. From the H-beta difference profiles we found that the radial velocity variations of the blue and red bumps and their differences are unticorrelated with the light curves of H-beta and continuum radiation. This implies that the zone that contributes most of the energy to the emitted line changes in radius within the disk. These transient phenomena are expected to result from the variable rate of accretion close to the central source. |
