The Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) is a deep wide-field multi-band imaging survey consisting of three layers (Wide, Deep, and UltraDeep), with the Wide layer…
Systematic Analysis of Changing-look AGN Variability Using ZTF Light Curves
Huimei Wang, Xue-Bing Wu, Nanyu Yao +5
Changing-look active galactic nuclei (CLAGNs) are a unique population of AGNs that exhibit the appearance (turn-on) or disappearance (turn-off) of broad emission lines. This study…
Quasar identifications from the slitless spectra: a test from 3D-HST
Yuxuan Pang, Xue-Bing Wu, Yuming Fu +4
Slitless spectroscopy is a traditional method for selecting quasars. In this paper, we develop a procedure for selecting quasars (QSOs) using the 3D-HST G141 slitless spectra. We i…

Yuxuan Pang, Xue-Bing Wu, Yuming Fu +4
The wide survey of the Chinese Space Station Telescope (CSST) will observe a large field of 17,500 . The GU, GV, and GI grism observations of CSST will cover a wavele…
The changing-look AGN SDSS J101152.98+544206.4 is returning to a type I state
Bing Lyu, Xue-Bing Wu, Yuxuan Pang +11
Aims. We reported the discovery that a changing-look AGN SDSS J101152.98+544206.4 (J1011+5442 for short) gradually returns to the type 1 state after a short period between 2014 and…
