| 英文摘要 | We re-examine the ten reverberation mapping (rm) sources with public data based on the two-component model of the broad line region (blr). in fitting their broad h beta mlines, six of them only need one gaussian component, one of them has a double-peak profile, one has an irregular profile, and only two of them need two components, i.e., a very broad gaussian component (vbgc) and an inter-mediate gaussian component (imgc). the gaussian components are assumed to come from two distinct regions in the two-component model; they are the very broad line region (vblr) and the inter-mediate line region (imlr). the two sources with a two-component profile are mrk 509 and ngc 4051. the time lags of the two components of both sources satisfy t(imlr)/t(vblr)=v(vblr)(2)/v(imlr)(2), where t(imlr) and t(vblr) are the lags of the two components while v(imlr) and v(vblr) represent the mean gas velocities of the two regions, supporting the two-component model of the blr of active galactic nuclei (agns). the fact that most of these ten sources only have the vbgc confirms the assumption that rm mainly measures the radius of the vblr; consequently, the radius obtained from the r-l relationship mainly represents the radius of vblr. moreover, ngc 4051, with a lag of about 5 days in the one component model, is an outlier on the r-l relationship as shown in kaspi et al. (2005); however this problem disappears in our two-component model with lags of about 2 and 6 days for the vbgc and imgc, respectively. |
