| 英文摘要 | The disk-jet symbiosis is a fundamental problem in our understanding of the Active Galactic Nuclei (AGN). We explore the relation between the Doppler factors delta of the jet of blazars and their broad line region luminosity L (BLR). Since different methods measuring delta might differ substantially, we use data obtained from 3 independent methods and compile 3 samples of sources for each of them, respectively. Two samples consist of blazars, that is, Flat Spectrum Radio Quasars (FSRQs) and BL Lacertae objects (BL Lacs), and the other consists of BL Lacs. delta is one of the most important jet properties and L (BLR) is thought to be the proxy of the accretion power. Correlation analysis to these samples shows that there exists a significant correlation between delta and L (BLR), which supports the idea that the jet powering process is closely linked with the accretion process and provides new evidence for disk-jet connection. Furthermore, the results are consistent with the idea that the Blandford-Znajek mechanism is sufficient for BL Lacs and a hybrid model is needed for FSRQs. |
