Implications of the nanoHertz Gravitational-Wave Background for Galactic Feedback and Massive Black Hole Growth

Megan Taylor Tillman, Blakesley Burkhart, Chiara M. F. Mingarelli +5

We investigate how pulsar timing array (PTA) measurements of the nanoHertz gravitational-wave background (GWB) can constrain models for the growth history of supermassive black hol…
