摘要:

对几个射电强(RL)窄线Seyfert 1(NLS 1)星系的γ射线探测,使我们能够研究活动星系核(AGN)中的强相对论喷流,这些星系核具有比经典耀变体小的黑洞质量和高的吸积率。然而,这些γ射线探测到的NLS 1的样本仍然不够大,无法进行全面的统计研究。我们总结了我们对三个γ射线发射NLS 1的探测和后续研究:SDSS J211852.96-073227.5,带闪烁γ射线辐射(Yang et al. 2018,Paliya et al. 2018)和SDSS J122222.55+041315.7,迄今为止红移最高(z~1)(Yao等人,2015 a),以及原型1H 0323+342(Zhou等人,2007,Yao等人,2015 b)。我们将讨论它们的多波长特性和变化特性,包括γ射线和X射线的高能观测,红外和无线电特性以及几个波段之间的相关变化。

英文摘要:

The γ-ray detection from several radio-loud (RL) narrow-line Seyfert 1 (NLS1) galaxies has enabled us to study powerful relativistic jets in active galactic nuclei (AGNs) with smaller black hole masses and higher accretion rates than classical blazars. However, the sample of those γ-ray detected NLS1s available is still not large enough for a comprehensive and statistical study. We provide a summary of our detections and follow-up studies of three γ-ray-emitting NLS1s: SDSS J211852.96-073227.5 with flaring γ-ray radiation (Yang et al. 2018, Paliya et al. 2018) and SDSS J122222.55+041315.7 with the highest redshift by far (z~1) (Yao et al. 2015a), along with the prototype 1H 0323+342 (Zhou et al. 2007, Yao et al. 2015b). And we will discuss their multiwavelength properties and variability properties, including implications from high-energy observations in γ-rays and X-rays, infrared and radio properties, and correlated variability between several wavebands.
