Un nuovo appuntamento con la serie "Seminari generali dell'IAC 2023" è previsto per mercoledì 31 maggio con Thibault Damour, pluripremiato professore emerito dell'IHES- Institut des Hautes Études ScientifiquesUniversité Paris-Saclay.
Il titolo del seminario è: Black hole binary dynamics and waveforms from (classical and/or quantum) gravitational scattering
Di seguito l'abstract.
This Gravitational wave signals from coalescing binary black holes are detected, and analyzed, by using large banks of template waveforms. The construction of these templates makes an essential use of the analytical knowledge of the motion and radiation of gravitationally interacting binary systems. A new angle of attack on gravitational dynamics consists of considering (classical or quantum) scattering states. Modern amplitude techniques have recently given interesting novel results. These results are reaching a level where subtle conceptual issues arise (quantum-classical transition, radiative effects versus conservative dynamics, massless limit,...).
