X-Ray Variability of SDSS J000532.84+200717.4: From a Normal State to an X-Ray Weak State

We present a multiepoch study of the extreme X-ray variability of the type 1 quasar SDSS J000532.84+200717.4 using archival observations from XMM-Newton, Swift/XRT, EP-FXT, and ROSAT, together with new optical spectroscopy and multiwavelength photometry. The 0.2–10 keV X-ray flux exhibits a transiti...
