GJC: Takuya Katagiri "On subtleties of theoretical modeling of relativistic dynamical tides"

Wednesday 2 Jul 2025, 13:00 → 14:00 Europe/Rome

Sala Fiore (Marconi)

Tidal interactions encode rich information about binary components in gravitational wave signals, allowing us to probe nuclear physics at supranuclear densities, test General Relativity, and investigate the fundamental nature of compact objects. Despite their significance, the theoretical modeling of relativistic tidal effects remains incomplete. In this talk, I will elucidate overlooked subtleties in the modeling of dynamical tides, in addition to the known ambiguities in static tides. Furthermore, I will propose a practical framework for extracting tidal parameters of non-black-hole objects from gravitational-wave observations.
