Title: "Supermassive black hole astrophysics with pulsar timing arrays"
Speaker: Prof. Alberto Sesana (Universita' di Milano)

The detection of gravitational waves (GWs) has opened a completely new window on the Universe. At nHz frequencies, pulsar timing arrays (PTAs) promise to detect the signal coming from the cosmological population of supermassive black hole binaries (SMBHBs) within the next few years. After reviewing the astrophysics of SMBHBs, I will describe the pulsar timing technique, the current status of the PTA effort, present the most recent results, and discuss their astrophysical implications.
