Boosted static multipole particles as sources of impulsive gravitational waves
Physical Review D, Particles and fields
It is shown that the known solutions for nonexpanding impulsive gravitational waves generated by null particles of arbitrary multipole structure can be obtained by boosting the Weyl solutions describing static sources with arbitrary multipole moments, at least in a Minkowski background. We also discuss the possibility of boosting static sources in (anti-) de Sitter backgrounds, for which exact solutions are not known, to obtain the known solutions for null multipole particles in these backgrounds.doi:10.1103/physrevd.58.124024 fatcat:cit2hsxhkbgd3omncf32hcjavu
