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,…

Gluon scattering on the self-dual dyon
Tim Adamo, Giuseppe Bogna, Lionel Mason +1
The computation of scattering amplitudes in the presence of non-trivial background gauge fields is an important but extremely difficult problem in quantum field theory. In even the…
