Possible γ-ray emission of radio intermediate AGN Ⅲ Zw 2 and its implication on the evolution of jets in AGNs被引量：1
《Research in Astronomy and Astrophysics》2010年第8期707-712,共6页Liang Chen Jin-Ming Bai Jin Zhang Hong-Tao Liu 
the West Ph.D. project of the Training Programme for the Talents of the West Light Foundation of the CAS;the National Natural Science Foundation of China (NSFC;Grant Nos.10903025 and 10778702) for financial support;the National Natural Science Foundation of China (Grant No.10973034);the 973 Program (Grant No.2009CB824800)
AGNs with hard γ-ray emission identified so far are radio-loud. Ⅲ Zw 2 is a radio intermediate AGN with a relativistic jet. We study its spectral energy distribution （SED） and find that the broad band emissions ar...

New insights into AGNs with low-mass black holes and high accretion rates:the case of narrow-line Seyfert 1 galaxies被引量：1
《Science China(Physics,Mechanics & Astronomy)》2010年第S1期216-219,共4页KOMOSSA S 
supported by the National Basic Research Program of China-973 (Grant No. 2009CB824800);the National Natural Science Foundation of China (Grant No. 10873017)
Narrow-line Seyfert 1(NLS1) galaxies are believed to harbor low-mass black holes accreting at high rates,and they are therefore important targets when studying the nature of black hole growth,galaxy evolution,and accr...

Progress of research on AGNs at the Urumqi Observatory
《Science China(Physics,Mechanics & Astronomy)》2010年第S1期244-246,共3页T.P.KRICHBAUM L.FUHRMANN N.MARCHILI 
supported by the National Basic Research Program of China (Grant No. 2009CB824800);the National Natural Science Foundation of China (Grant No. 10773019)
We report the progress on Very Long Baseline Interferometry(VLBI) observations of Gigahertz Peaked Spectrum(GPS) radio sources,and single-dish observations of active galactic nuclei(AGNs).The GPS sources are a kind of...

We re-examine the ten Reverberation Mapping(RM) sources with public data based on the two-component model of the Broad Line Region(BLR).In fitting their broad Hβ Mlines,six of them only need one Gaussian component,on...
