WebWe present a review of the topics of X-ray stellar tidal disruption events (TDEs) and changing-look active galactic nuclei (AGN). Stars approaching a supermassive black hole (SMBH) can be tidally disrupted and accreted. TDEs were first discovered in the X-ray regime and appear as luminous, giant-amplitude flares from inactive galaxies. The early … WebThe transition in optical changing-look AGN is still not fully understood. The favoured scenario in most of the studies mentioned above is that this transition is due to a change in mass accretion rate as opposed to changes in obscuration (e.g. Sheng et al. 2024; Stern et al. 2024).
