Aberration of gravitational waveforms by peculiar velocity

Camille Bonvin, Giulia Cusin, Cyril Pitrou +3

One key prediction of General Relativity is that gravitational waves are emitted with a pure spin-2 polarisation. Any extra polarisation mode, spin-1 or spin-0, is consequently con…

Carrollian conformal scalar as flat-space singleton

Xavier Bekaert, Andrea Campoleoni, Simon Pekar

We show that, in any space-time dimension, the on-shell (electric) conformal Carrollian scalar can be interpreted as the flat-space limit of the singleton representation of the con…
