Mrk 382: A Narrow-line Seyfert 1 Galaxy with Recurrent X-Ray State Transitions

Abstract We report recurrent X-ray state transitions in the nearby narrow-line Seyfert 1 galaxy Mrk 382 using multiepoch observations from Swift, Chandra, XMM-Newton, and eROSITA, together with archival ultraviolet (UV), optical, and infrared (IR) data. The 0.3–2 keV flux varies...

In-flight calibration of the Wide-field X-ray Telescope on board the Einstein Probe

By utilizing novel lobster-eye optics, the Wide-field X-ray Telescope (WXT) on board the Probe satellite achieves an unprecedented combination of a large instantaneous field of view (FoV) and high sensitivity for monitoring the dynamic X-ray sky. In this paper, we present the in-...
