Back from the dead: AT2019aalc as a candidate repeating tidal disruption event in an active galactic nucleus

Context. To date, three nuclear transients have been associated with high-energy neutrino events. These transients are generally thought to be powered by tidal disruption events (TDEs) in stars caused by massive black holes. However, AT2019aalc, hosted in a Seyfert-1 galaxy, has not yet been classif...
