Celestial holography: An asymptotic symmetry perspective
Laura Donnay
We review the role that infinite-dimensional symmetries arising at the boundary of asymptotically flat spacetimes play in the context of the celestial holography program. Once reca…
Inferring fundamental spacetime symmetries with gravitational-wave memory: from LISA to the Einstein Telescope
Boris Goncharov, Laura Donnay, Jan Harms
We revisit gravitational wave (GW) memory as the key to measuring spacetime symmetries, extending beyond its traditional role in GW searches. In particular, we show how these symme…
Logarithmic soft graviton theorems from superrotation Ward identities
Shreyansh Agrawal, Laura Donnay, Kevin Nguyen +1
Soft graviton theorems receive one-loop contributions that are logarithmic in the energy of the soft graviton, and which are closely related to tails of gravitational waveforms. We…
Celestial open strings at one-loop
Laura Donnay, Gaston Giribet, Hernán González +2
We study celestial amplitudes in string theory at one-loop. Celestial amplitudes describe scattering processes of boost eigenstates and relate to amplitudes in the more standard ba…
