SUMMARY: The path to coalescence of massive black hole binaries across tim

DESCRIPTION:Coalescing massive black hole binaries are key targets for sev
 eral ongoing and planned gravitational wave facilities\, such as Pulsar Ti
 ming Arrays and the LISA mission. These observatories promise to probe the
  properties of merging massive black holes across the evolution of our Uni
 verse\, unveiling the clustering and growth of massive black holes and the
 ir host galaxies all the way up to the cosmic dawn. In this seminar\, I wi
 ll describe the new advances and challenges in the modelling of the path t
 o coalescence of massive black hole binaries. I will especially focus on r
 ecent results that challenge the traditional paradigm of binary evolution\
 , from the\nlarge-scale galaxy merger down to the small separations at whi
 ch the evolution is dominated by stellar hardening\, interactions with a g
 aseous disk and\, finally\, gravitational-wave emission. I will conclude b
 y  discussing the critical importance of constructing realistic models for
  the galaxy hosts of massive binaries to properly\nassess the detection pr
 ospects of upcoming gravitational-wave detectors.
