AT2018fyk: Candidate Tidal Disruption Event by a (Super)Massive Black Hole Binary
The tidal disruption event (TDE) AT2018fyk has unusual X-ray, UV, and optical light curves that decay over the first ∼600 days, rebrighten, and decay again around 1200 days. We explain this behavior as a one-off TDE associated with a massive black hole (BH) binary . The sharp drop-offs from t ^−5/3...
