Within this decade the detection of gravitational waves (GWs) may be a reality, opening a completely new window on the Universe. The low frequency window will be dominated by signals emitted by a cosmological population of massive black hole binaries (MBHBs). In this talk I will review several aspect of MBH physics, including their formation, evolution, interaction with their environment and gravitational wave (GW) emission. I will pay particular attention to the prospect of GW detection with pulsar timing arrays and/or future space based interferometers.
Followed by wine and cheese in Pupin 1402.
