论文摘要
伽马射线爆发（GRB）和活性银河核（AGN）的高能量光子辐射由它们的射流辐射支配。我们检查了BL LAC中喷气机的同步辐射，平面无线电类星体（FSRQ）和狭窄的线Seyfert 1星系（NLS1S）遵循及时伽马射线发射与初始Lorentz因子（$γ_0$）GRB的及时伽马射线发射之间的关系。结果表明，AGNS样本与$ l _ {\ rm p} -e _ _ {\ rm p，z}-γ_{0} $不一致。此外，我们获得了$ l _ {\ rm syn} \ propto e^{0.45 \ pm0.15} _ {\ rm syn，p}Δ^{3.50 \ pm0.25} $ fsrqs and nls1 galles premin，$ lm syn} $ e _ {\ rm syn，p} $的同步子辐射。此关系与$ l _ {\ rm p} -e _ {\ rm p，z}-γ_{0} $ grbs的关系。 $ l _ {\ rm syn} $对$δ$的依赖性与FSRQ和NLS1星系的多普勒增强效果的期望一致，但这不是GBRS。我们认为，$γ_0$可能是辐射区域动力的代表，而紧密的$ l _ {\ rm p} -e _ _ {\ rm P，z}-γ_0$关系由辐射物理学和喷气功率组合在一起。
High energy photon radiations of gamma-ray bursts (GRBs) and active galactic nuclei (AGNs) are dominated by their jet radiations. We examine wether the synchrotron radiations of jets in BL Lacs, flat spectrum radio quasars (FSRQs), and Narrow Line Seyfert 1 galaxies (NLS1s) follow the relation between the prompt gamma-ray emission and the initial Lorentz factor ($Γ_0$) of GRBs. It is showed that the AGNs sample does not agree with the $L_{\rm p}-E_{\rm p,z}-Γ_{0}$ of GRBs. In addition, we obtain a tight relation of $L_{\rm syn}\propto E^{0.45\pm0.15}_{\rm syn,p}δ^{3.50\pm0.25}$ for FSRQs and NLS1 galaxies, where $L_{\rm syn}$ is the luminosity at peak photon energy $E_{\rm syn, p}$ of the synchrotron radiations. This relation is different from the $L_{\rm p}-E_{\rm p,z}-Γ_{0}$ relation of GRBs. The dependence of $L_{\rm syn}$ to $δ$ is consistent with the expectation of the Doppler boosting effect for the FSRQs and NLS1 galaxies, but it is not for GBRs. We argue that $Γ_0$ may be a representative of the kinetic power of the radiating region and the tight $L_{\rm p}-E_{\rm p, z}-Γ_0$ relation is shaped by the radiation physics and the jet power together.
