Tidal disruption events (TDEs) are not the primary power source for most observed active galactic nuclei (AGNs) in dwarf galaxies.

Tidal Disruption Events Are Unlikely to Be the Dominant Power Source for Active Galactic Nuclei in Dwarf Galaxies

The detection of quasi-periodic X-ray eruptions from a known tidal disruption event suggests that these eruptions could be caused by an orbiting body colliding with the accretion disk formed after a star is disrupted by a supermassive black hole.


The detection and modelling of nine X-ray quasi-periodic eruptions from a nearby tidal disruption event shows that these eruptions arise in accretion disks around massive black holes, left behind by tidally disrupted stars, and that an orbiting body colliding with this disk is a plausible explanation for the X-ray variability.

Quasi-periodic X-ray eruptions detected years after a tidal disruption event: Evidence for an orbiting body colliding with an accretion disk



The observation of two optical flares separated by 10.3 years in the galaxy IRAS F01004-2237 suggests the occurrence of recurring tidal disruption events (TDEs), potentially caused by repeating partial TDEs, double TDEs, or two independent TDEs.
