Abstract

The authors describe a class of impulsive gravitational waves which propagate either in a de Sitter or an anti - de Sitter background. These are conformal to impulsive waves of Kundt's class. In a background with positive cosmological constant, they are spherical (but nonexpanding) waves generated by pairs of particles with arbitrary multipole structure propagating in opposite directions. When the cosmological constant is negative, they are hyperboloidal waves generated by a null particle of the same type. In this case, they are included in the impulsive limit of a class of solutions described by Siklos (1985) that are conformal to pp-waves.
