Graviton scattering on self-dual black holes
Tim Adamo, Giuseppe Bogna, Lionel Mason +1
The computation of gravitational wave scattering on black hole spacetimes is an extremely hard problem, typically requiring approximation schemes that either treat the black hole p…

Towards celestial chiral algebras of self-dual black holes
Giuseppe Bogna, Simon Heuveline
In this note, we show that several self-dual spacetimes previously studied in the context of celestial and twisted holography arise as limits of a certain Taub-NUT AdS metric,…

Scattering on self-dual Taub-NUT
Tim Adamo, Giuseppe Bogna, Lionel Mason +1
We derive exact solutions of massless free field equations and tree-level two-point amplitudes up to spin 2 on self-dual Taub-NUT space-time, as well as on its single copy, the sel…
