| 英文摘要 | By modeling the broadband spectral energy distributions (SEDs) of a typical flat spectrum radio quasar (FSRQ, 3C 279) and two GeV narrow-line Seyfert 1 galaxies (NLS1s, PMN J0948+0022 and 1H 0323+342) in different flux stages with one-zone leptonic models, we find a universal correlation between their Doppler factors (delta) and peak luminosities (L-c) of external Compton scattering bumps. Compiling a combined sample of FSRQs and GeV NLS 1 s, it is found that both FSRQs and GeV NLS ls in different stages and in different sources follow the same delta-L-c correlation well. This indicates that the variations of observed luminosities may be essentially due to the Doppler boosting effect. The universal delta-L-c relation between FSRQs and GeV NLS ls in different stages may be further evidence that the particle acceleration and radiation mechanisms for the two kinds of sources are similar. In addition, by replacing L-c with the observed luminosity in the FennilLAT band (L-LAT), this correlation holds and it may serve as an empirical indicator of delta. We estimate the delta values with L-LAT for 484 FSRQs in the FennilLAT Catalog and they range from 3 to 41, with a median of 16, which are statistically consistent with the values derived by other methods. |
