Core-dominance parameter, black hole mass and jet-disc connection in Fermi blazars

Y. Y. Chen, X. Zhang, H. J. Zhang, X. L. Yu

摘要:

我们分别研究了费米耀变体和非费米耀变体的喷注功率与吸积之间的关系。并对它们的相关参数进行了比较。我们的主要结果如下。(i)费米耀变体和非费米耀变体在红移、黑洞质量和宽线光度上有显著差异。(ii)费米耀变体的平均核心优势参数比非费米耀变体高,表明费米耀变体具有较强的聚束效应。(iii)我们发现费米和非费米耀变体的宽线发射和喷流功率之间存在显著的相关性,这表明喷流和吸积之间存在直接的紧密联系。(iv)吸积和黑洞质量对费米耀变体和非费米耀变体喷流功率的贡献可能不同。

英文摘要:

We study the relationship between jet power and accretion for Fermi and non-Fermi blazars, respectively. We also compare the relevant parameter between them. Our main results are as follows. (i) Fermi and non-Fermi blazars have significant difference in redshift, black hole mass, and broad line luminosity. (ii) Fermi blazars have higher average core-dominance parameter than non-Fermi blazars, which suggests that Fermi blazars have strong beaming effect. (iii) We find significant correlation between broad line emission and jet power for Fermi and non-Fermi blazars, respectively, which suggests a direct tight connection between jet and accretion. (iv) The accretion and black hole mass may have a different contribution to jet power for Fermi and non-Fermi blazars, respectively.
