A Tidal Disruption Event from an Intermediate-mass Black Hole Revealed by Comprehensive Multi-wavelength Observations
Jialai Wang, Mengqiu Huang, Yongquan Xue +12
Tidal disruption events (TDEs) occur when a star crosses the tidal radius of a black hole (BH) and is ripped apart, providing a powerful way to probe dormant BHs over a wide mass r…
The Drivers of the Decline in Supermassive Black Hole Growth at
Zhibo Yu, W. N. Brandt, Fan Zou +4
It is well established that cosmic supermassive black hole (SMBH) growth peaks at , followed by a strong decline of toward the present day, w…
The Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?
Mengqiu Huang, Yongquan Xue, Shuo Li +30
Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…
The Nature of an Unidentified X-ray Source in the 7 Ms Chandra Deep Field-South Catalog
Quinn P. Sullivan, Zhibo Yu, William N. Brandt +2
In the 7 Ms Chandra Deep Field-South catalog, only one source, XID 912, was highly significantly detected in X-rays but had no formally reported counterparts in the UV, optical, in…
Photometric Selection of type 1 Quasars in the XMM-LSS Field with Machine Learning and the Disk-Corona Connection
Jian Huang, Bin Luo, W. N. Brandt +4
We present photometric selection of type 1 quasars in the XMM-Large Scale Structure (XMM-LSS) survey field with machine learning. We constructed our trai…
