(SMBHs) emerged within the </div><div class="">first billion years after the Big Bang is an
unsolved puzzle. I will present a multi-messenger project </div><div class="">to tackle this
question, which combines multi-scale cosmological simulations,
multi-wavelength </div><div class="">radiative transfer and multi-phase gravitational waves.
I will present viable formation models of the </div><div class="">first SMBHs, and
demonstrate that a light-and-sound synergy between future
electromagnetic telescopes, </div><div class="">such as JWST, and gravitational waves
detectors, such as LISA, is necessary to test models of black hole </div><div class="">seed
and growth path of the first SMBHs.</div><div class=""><br class=""></div><div class=""><a href="https://agenda.infn.it/event/21921/" class="">https://agenda.infn.it/event/21921/</a></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><br class=""><br class=""><br class=""><br class="">
