Peeling-violating coefficients in classical gravitational scattering
Gianni Boschetti, Miguel Campiglia
Using matching properties of the gravitational field at timelike and spatial infinity, together with universal formulas for gravitational wave tails, we obtain exact expressions fo…
An asymptotic proof of the classical log soft graviton theorem
Gianni Boschetti, Miguel Campiglia
We present a derivation of the classical log soft graviton theorem within the asymptotic framework of Compère, Gralla, and Wei. The proof relies solely on Einstein equations near…
Log translation invariance of log soft gravitational radiation
Gianni Boschetti, Miguel Campiglia
The gravitational radiation emitted during a classical scattering process is known to exhibit two universal logarithmic terms in its soft frequency expansion. We show that these te…
Gravitational Poisson brackets at null infinity compatible with smooth superrotations
Miguel Campiglia, Adarsh Sudhakar
Superrotations are local extensions of the Lorentz group at null infinity that have been argued to be symmetries of gravitational scattering. In their smooth version, they can be i…
