Outflows from active galactic nuclei: The BLR-NLR metallicity correlation
Pu Du, Jian-Min Wang, Chen Hu +4
The metallicity of active galactic nuclei (AGNs), which can be measured by emission line ratios in their broad and narrow line regions (BLRs and NLRs), provides invaluable informat…
Supermassive black holes with high accretion rates in active galactic nuclei: I. First results from a new reverberation mapping campaign
P. Du, C. Hu, K. -X. Lu +7
We report first results from a large project to measure black hole (BH) mass in high accretion rate active galactic nuclei (AGNs). Such objects may be different from other AGNs in…
A Bayesian Approach to Estimate the Size and Structure of the Broad-line Region in Active Galactic Nuclei Using Reverberation Mapping Data
Yan-Rong Li, Jian-Min Wang, Luis C. Ho +2
This is the first paper in a series devoted to systematic study of the size and structure of the broad-line region (BLR) in active galactic nuclei (AGNs) using reverberation mappin…
The hard X-ray behavior of Aql X-1 during type-I bursts
Yu-Peng Chen, Shu Zhang, Shuang-Nan Zhang +5
We report the discovery of an anti-correlation between the soft and the hard X-ray lightcurves of the X-ray binary Aql X-1 when bursting. This behavior may indicate that the corona…
X-ray bursts as a probe of the corona: the case of XRB 4U 1636-536
Long Ji, Shu Zhang, YuPeng Chen +6
To investigate the possible cooling of the corona by soft X-rays bursts, we have studied 114 bursts embedded in the known X-ray evolution of 4U 1636-536. We have grouped these burs…
Type-I X-ray bursts reveal a fast co-evolving behavior of the corona in an X-ray binary
Yu-Peng Chen, Shu Zhang, Shuang-Nan Zhang +2
The coronae in X-ray binaries (XRBs) still remain poorly understood, although they have been believed for a long time to play a key role in modeling the characteristic outbursts of…
