Introduction to the special issue dedicated to Michael J. Duff FRS on the occasion of his 70th birthday
L. Borsten, A. Marrani, C. N. Pope +1
This special feature, dedicated to Michael J. Duff FRS on the occasion of his 70th birthday, concerns topics in 'Quantum gravity, branes and M-theory'. These three intertwining sub…
Asymptotic Weyl Double Copy
Hadi Godazgar, Mahdi Godazgar, Ricardo Monteiro +2
A characteristic value formulation of the Weyl double copy leads to an asymptotic formulation. We find that the Weyl double copy holds asymptotically in cases where the full soluti…
Taub-NUT from the Dirac monopole
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
Writing the metric of an asymptotically flat spacetime in Bondi coordinates provides an elegant way of formulating the Einstein equation as a characteristic value problem. In this…
Dual gravitational charges and soft theorems
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
We consider the consequences of the dual gravitational charges for the phase space of radiating modes, and find that they imply a new soft NUT theorem. In particular, we argue that…
New dual gravitational charges
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
We show that there are a further infinite number of, previously unknown, supertranslation charges. These can be viewed as duals of the known BMS charges corresponding to supertrans…
Tower of subleading dual BMS charges
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
We supplement the recently found dual gravitational charges with dual charges for the whole BMS symmetry algebra. Furthermore, we extend the dual charges away from null infinity, d…
