论文摘要
2008年发现了狭窄的Seyfert 1星系（NLS1）的高能量伽马射线的发现，清楚地表明，除了弹性核（AGN）以外，有活跃的银河核（AGN）和可以弹出强大的相关性射击。除了NLS1之外，费米大面积望远镜的出色表现使发现从更多类别的AGN发出的MEV-GEV光子，例如Seyferts，紧凑型陡峭的Spectrum Gigahertz峰（CSS/GPS）和磁盘供应的射电射线星系。尽管观察结果表明了各种物体，但它们的物理特征表明中央发动机由相对较小的黑洞提供动力（但显然有这种观点的解释）。本文批判性地回顾了过去八年中有关这些主题的文献，并分析了即将到来的几年的观点。
The discovery in 2008 of high-energy gamma-rays from Narrow-Line Seyfert 1 Galaxies (NLS1s) made it clear that there were active galactic nuclei (AGN) other than blazars and radio galaxies that can eject powerful relativistic jets. In addition to NLS1s, the great performance of the Fermi Large Area Telescope made it possible to discover MeV-GeV photons emitted from more classes of AGN, like Seyferts, Compact Steep Spectrum Gigahertz Peaked Sources (CSS/GPS), and disk-hosted radio galaxies. Although observations indicate a variety of objects, their physical characteristics point to a central engine powered by a relatively small-mass black hole (but, obviously, there are interpretations against this view). This essay critically reviews the literature published on these topics during the last eight years and analyses the perspectives for the forthcoming years.
