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…
Subleading BMS charges and fake news near null infinity
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
In this paper we establish a relation between the non-linearly conserved Newman-Penrose charges and certain subleading terms in a large- expansion of the BMS charges in an asymp…
Penrose quasi-local energy and Kerr-Schild metrics
Mahdi Godazgar, Andre Kaderli
Specialising to the case of Kerr-Schild spacetimes, which include the Kerr black hole and gravitational wave solutions, we propose a modification of the Penrose quasi-local energy.…
