摘要:

本文介绍了两个邻近的赛弗特2星系的硬X射线(> 10 keV)观测结果。这两个来源都清楚地检测到PIN硬X射线探测器高达几十千电子伏,允许一个相当好的表征宽带X射线连续。这两个源都被严重遮蔽,其中一个(NGC 5728)是康普顿厚度,而在较低的能量下,散射/反射连续谱的形状和强度是非常不同的。在两种来源中都检测到强铁Kalpha线。在NGC 4992中也有一条宽的相对论性铁谱线。

英文摘要:

Suzaku observations of two hard X-ray (> 10 keV) selected nearby Seyfert 2 galaxies are presented. Both sources were clearly detected with the PIN Hard X-ray Detector up to several tens of keV, allowing for a fairly good characterization of the broad band X-ray continuum. Both sources are heavily obscured, one of which (NGC 5728) being Compton thick, while at lower energies the shape and intensity of the scattered/reflected continuum is very different. Strong iron Kalpha lines are detected in both sources. There are also hints for the presence of a broad relativistic iron line in NGC 4992.
