Abstract:
Massive black holes weighing from a few tens of thousands to tens of 
billions of solar masses inhabit the centers of today’s galaxies, 
including our own Milky Way. Massive black holes also shone as quasars 
in the past, with the earliest detected a mere billion years after the 
Big Bang. Along cosmic time, encounters between galaxies hosting massive 
black holes in their centers are expected to have produced binary 
massive black holes that eventually coalesced by emission of 
gravitational waves. I will discuss the physical processes through which 
massive black holes pair and bind, and how we can use gravitational wave 
observations with ESA’s planned satellite LISA to constrain the evolving 
population of massive black holes.
