| 英文摘要 | We present a spectral analysis for a sample of redshift-known gamma-ray bursts (GRBs) observed with Fermi/GBM. Together with the results derived from our systematical spectral energy distribution modeling with the leptonic models for a Fermi/LAT blazar sample, we compare the distributions of the GRBs and the blazars by plotting the synchrotron peak luminosity (L-s) and the corresponding peak photon energy E-s of blazars in the L-p-E-p-plane of GRBs, where L-p and E-p are the peak luminosity and peak photon energy of the GRB time-integrated nu f(nu) spectrum, respectively. The GRBs are in the high-L-p, high-E-p corner of the plane and a tight L-p-E-p relation is found, i.e., L-p alpha E-p(2.13-0.46) (+0.54). Both flat spectrum radio quasars (FSRQs) and low-synchrotron peaking BL Lac objects (LBLs) are clustered in the low-Ep, low-Lp corner. Intermediate-and high-synchrotron peaking BL Lac objects (IBLs and HBLs) have E-s similar to 2 x 10(-3)-10(2) keV and L-s similar to 10(44)-10(47) erg s(-1), but no dependence of L-s on E-s is found. We show that the tight L-p-E-p relation of GRBs is potentially explained with the synchrotron radiation of fast-cooling electrons in a highly magnetized ejecta, and the weak anti-correlation of L-s-E-s for FSRQs and LBLs may be attributed to synchrotron radiation of slow-cooling electrons in a moderately magnetized ejecta. The distributions of IBLs and HBLs in the L-p-E-p-plane may be interpreted with synchrotron radiation of fast-cooling electrons in a matter-dominated ejecta. These results may present a unified picture for the radiation physics of relativistic jets in GRBs and blazars within the framework of the leptonic synchrotron radiation models. |
