Approximate Models for Gravitational Memory
Q-L Zhao, P. -M. Zhang, M. Elbistan +1
The large-distance approximation of a sandwich gravitational wave by a continuous but not necessarily smooth profile provides us with an approximate analytic description of particl…

Gravitational wave memory: further examples
P. -M. Zhang, Q. -L. Zhao, M. Elbistan +1
Ehlers and Kundt [1] argued in favor of the velocity effect: particles initally at rest hit by a burst of gravitational waves should fly apart with constant velocity after the wave…

Displacement memory for flyby
P. -M. Zhang, Q. -L. Zhao, J. Balog +1
Zel'dovich and Polnarev, in their seminal paper [1] suggested that a gravitational wave generated by flyby would merely displace the particles. We confirm their prediction numerica…
