TDE rates from recoiling MBHs ejected by triple interactions

Determine the tidal disruption event rate produced by massive black holes that recoil due to three–massive–black–hole (triple) interactions via gravitational slingshot ejection, quantifying how this rate depends on the bound star cluster carried with the recoiling black hole and its galactocentric separation.

Background

In the discussion of formation scenarios for the off-nuclear tidal disruption event AT2024tvd, the authors consider a mechanism in which a massive black hole is ejected from a triple system (gravitational slingshot) and subsequently produces tidal disruption events while wandering at kiloparsec-scale offsets from the galactic center.

The paper notes that while related work has modeled TDE rates from gravitational-wave–kicked (recoiling) MBHs, the specific case of slingshot-ejected MBHs lacks dedicated theoretical treatment. Establishing the TDE rate in this scenario would inform whether such events can plausibly account for observed off-nuclear TDEs and guide future searches.
