射电强窄线Seyfert 1作为Gamma-Ray AGN的新类

Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN

LAT Collaboration, G. Ghisellini, L. Maraschi, F. Tavecchio

摘要:

本文报道了Fermi/LAT在PKS 1502+036(z=0.409)、1H 0323+342(z =0.061)和PKS 2004-447(z=0.24)三个射电强窄线Seyfert 1星系中发现的γ射线辐射。除了PMN J 0948 +0022(z=0.585),第一个在伽马射线中被探测到的这种类型的源,它们可能形成一个新兴的新的伽马射线活动星系核(AGN)。这些发现对我们对相对论喷流和活动星系核统一模型的认识有重要意义。

英文摘要:

We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z=0.24). In addition to PMN J0948+0022 (z=0.585), the first source of this type to be detected in gamma rays, they may form an emerging new class of gamma-ray active galactic nuclei (AGN). These findings can have strong implications on our knowledge about relativistic jets and the unified model of AGN.
