摘要 我们利用伽马射线窄线Seyfert 1星系（γ -NLS1s）的大样本来研究喷流形成机制。我们发现γ-NLS1s的喷射功率低于Blandford-Payne（BP）机构的最大喷射功率。同时，我们发现喷流功率与吸积盘光度之间存在显着的相关性。而且，吸积对喷流功率的贡献率大于黑洞质量对喷流功率的贡献率。这些结果进一步表明γ NLS1s的射流主要是由BP机制产生的。
Abstract We use a large sample of gamma-ray narrow-line Seyfert 1 galaxies ( γ -NLS1s) to study the jet formation mechanisms. We find that the jet power of γ -NLS1s is lower than the maximum jet power of the Blandford–Payne (BP) mechanism. At the same time, we find that there is a significant correlation between jet power and accretion disk luminosity. Moreover, the contribution rates of the accretion to the jet power are larger than that of black hole mass to jet power. These results further suggest that the jet of γ NLS1s is mainly produced by the BP mechanism.
