Centre for Geometry, Analysis and Gravitation Title: Reconstructions of space-times from scattering data. Abstract: I address the problem of reconstructing space-times from measurements of their scattering data for suitable wave equations on the background geometry. For linear waves, the reconstruction allows one to reconstruct just the operator itself, assuming knowledge of the background geometry; moreover the best results deal with ``finite'' scattering, where measurements do no occur at infinity, but rather on a suitably long... |

| Mon 7 Jul 2025 |  2pm Seminar: Adrian Chung, METRICS as a bridge between black-hole ringdown signals and fundamental physicsCentre for Geometry, Analysis and Gravitation Abstract: Many of the gravitational-wave signals detected by the LIGO-Virgo-KAGRA detectors end with exponentially decaying waves emitted by the remnant black holes formed by the corresponding binary black-hole coalescence. The frequencies and lifetimes of these decaying waves are called quasinormal mode frequencies, and they are closely related to the dynamics of the spacetime near the horizon of the remnant black hole. In this connection, detecting black-hole quasinormal modes is a powerful... |
