An X-ray study of changing-look active galactic nuclei

Titarchuk, Lev; Seifina, Elena; Mishin, Egor

A significant number of changing-look active galactic nuclei (CL AGNs) have been identified to date. In this work, we study what happens to the X-ray spectrum during CL events. We use the example of the nearby CL Seyfert named NGC 1566, which has been observed by Swift, NuSTAR, XMM-Newton, and Suzaku. We applied the Comptonization model to describ…
