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 ......
