Description

Tidal disruption events (TDEs) take place when a star orbiting around a black hole (BH) is fully or partially disrupted by the black hole tides. This occurrence can be used as a way to reveal the presence of quiescent BHs through the Universe. With this talk, I will first describe general features of TDEs. Then, I will explore the possibility of detecting them via gravitational waves (GWs) with future space-based interferometers. Finally, I will illustrate how the GW background from these events could allow us to better constrain the elusive population of intermediate-mass BHs and to map their distribution up to redshift 3.
