Implications of infalling Fe II - emitting clouds in active galactic nuclei: anisotropic properties
Gary J. Ferland, Chen Hu, Jian-Min Wang +4
We investigate consequences of the discovery that Fe II emission in quasars, one of the spectroscopic signatures of "Eigenvector 1", may originate in infalling clouds. Eigenvector…
INTEGRAL and Swift/XRT observations of IGR J19405-3016
Shu Zhang, Yu-Peng Chen, Diego F. Torres +3
IGR J19405-3016 is reported in the 3rd IBIS catalog as being one of its lowest significance sources (~4.6 sigma under an exposure of about 371 ks). This leads to a caveat in multi-…
Evolution of gaseous disk viscosity driven by supernova explosion in star-forming galaxies at high redshift
Jian-Min Wang, Chang-Shuo Yan, Yan-Rong Li +5
Motivated by Genzel et al.'s observations of high-redshift star-forming galaxies, containing clumpy and turbulent rings or disks, we build a set of equations describing the dynamic…
INTEGRAL and Swift/XRT observations of IGR~J16460+0849
Shu Zhang, Yupeng Chen, Jianmin Wang +2
IGR J16460+0849 is reported in the 3rd IBIS catalog with the shortest exposure of about 10 ks among all the detected sources, which makes it the most interesting target to be inves…
Outbursts from IGR J17473-2721
Shu Zhang, Yu-peng Chen, Jian-Min Wang +2
We have investigated the outbursts of IGR J17473-2721. We analyzed all available observations carried out by RXTE on IGR J17473-2721 during its later outburst and as well all the a…
Constraining spins of supermassive black holes from TeV variability. II. fully general relativistic calculations
Yan-Rong Li, Ye-Fei Yuan, Jian-Min Wang +2
The fast variability of energetic TeV photons from the center of M87 has been detected, offering a new clue to estimate spins of supermassive black holes (SMBHs). We extend the stu…
