Title: Late-time tails for linear waves on subextremal black hole spacetimes

Abstract: I will present some recent work (that has been done jointly with Stefanos Aretakis and Dejan Gajic) on the precise asymptotics of linear waves on the exterior (up to and including the event horizon) of subextremal black holes. Particular examples of such spacetimes are the full subextremal families of Reissner-Nordstrom and Kerr black hole spacetimes. I will also discuss the special case of linear waves localized in angular frequency, and I will talk about some potential applications.
