In this paper, we use a method to determine some basic parameters for the (r)-ray loud blazars. The parameters include t......
The XMM-Newton observations of H2O megamaser galaxy NGC 7479 are presented.Its smoothed X-ray image clearly shows spiral......
By analyzing Chandra X-ray data of a sample of 21 galaxy groups and 19galaxy clusters,we find that in 31 sample systems ......
Possible γ-ray emission of radio intermediate AGN Ⅲ Zw 2 and its implication on the evolution of jet
AGNs with hard γ-ray emission identified so far are radio-loud. Ⅲ Zw 2 is a radio intermediate AGN with a relativistic......
The external Compton (EC) model is used to study the high energy emission of some blazars,in which the external photon f......
We employ a sample of 362 flat-spectrum radio quasars (FSRQs) to calculate their integrated luminosities by integrating ......
自从人们获得河外射电源的第一个结构图像以来，３０多年时间已经过去了。在这段时间的后半期，人们对许多源中的喷流状结构作了大量研究。......
活动星系统的多波段观测和研究，早已成为天体物理学最热门的前沿之一。在射电天文学中，按其观测形态又常将ＡＧＮ和致密射电核等同看待。对......
使用一个具有(准)同时性宽带能谱数据的Fermi耀变体样本,对其进行同步和逆康普顿峰峰值参量、康普顿主导以及高能谱指数等参量之间......
采用活动星系核图像的核球／盘分解数据得到核球R波段光度值，计算了一个X射线活动星系核样本的中心大质量黑洞质量与核球质量之比（Mhh／M......
ＡＧＮ天体的主要特征之一，就是它们的光谱中有宽而强的发射线，因此，这些宽发射线的产生区域ＢＬＲ为人们提供了一个了解ＡＧＮ天体物理本质的独特而重要......
High resolution deep imaging from space and adaptive optics techniques with large ground-based facilities have enabled s......
