The NuSTAR view of five changing-look active galactic nuclei
Bing Lyu, Zhen Yan, Xue-bing Wu +3
Changing-look active galactic nuclei (CLAGNs) are known to change their spectral type between 1 and 2 (changing-state) or change their absorption between Compton-thick and Compton-…

Long-term and multi-wavelength evolution of a changing-look AGN Mrk 1018
Bing Lyu, Zhen Yan, Wenfei Yu +1
The physical mechanism for triggering the changing-look phenomenon in active galactic nuclei (AGNs) is still unclear. We explore this issue based on the multi-wavelength spectral a…

Evidence for changing-look AGNs is caused by change of accretion mode
Hao liu, Qingwen Wu, Bing Lyu +1
The discovery of changing-look active galactic nuclei (CL AGNs), with appearance and disappearance of broad emission lines and/or with strong variation of line-of-sight column dens…
