X-ray absorption and 9.7 um silicate feature as a probe of AGN torus structure
Jun Xu, Mouyuan Sun, Yongquan Xue +2
The dusty torus plays a vital role in unifying active galactic nuclei (AGNs). However, the physical structure of the torus remains largely unclear. Here we present a systematical i…
On the Origin of the Dramatic Spectral Variability of WPVS 007
Junyao Li, Mouyuan Sun, Tinggui Wang +2
We report the discovery of large-amplitude mid-infrared variabilities (MIR; mag) in the Wide-field Infrared Survey Explorer W1 and W2 bands of the low-luminosity narrow-…
A magnetar-powered X-ray transient as the aftermath of a binary neutron-star merger
Y. Q. Xue, X. C. Zheng, Y. Li +14
Neutron star-neutron star mergers are known to be associated with short gamma-ray bursts. If the neutron star equation of state is sufficiently stiff, at least some of such mergers…
Piercing Through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields: I. X-ray Spectral and Long-term Variability Analyses
Junyao Li, Yongquan Xue, Mouyuan Sun +13
We present a detailed X-ray spectral analysis of 1152 AGNs selected in the Chandra Deep Fields (CDFs), in order to identify highly obscured AGNs (…
Deepest view of AGN X-ray variability with the 7 Ms Chandra Deep Field-South survey
X. C. Zheng, Y. Q. Xue, W. N. Brandt +13
We systematically analyze X-ray variability of active galactic nuclei (AGNs) in the 7~Ms \textit{Chandra} Deep Field-South survey. On the longest timescale ( years), we…
