Defining higher memory signals and forecasting their observation prospects for binary-black-hole mergers with next-generation gravitational-wave detectors
Siddhant Siddhant, Alexander M. Grant, David A. Nichols
In asymptotically flat spacetimes far from an isolated source, gravitational waves (GWs) undergo nonlinear interactions with themselves and with the parts of the spacetime curvatur…
Higher memory effects and the post-Newtonian calculation of their gravitational-wave signals
Siddhant Siddhant, Alexander M. Grant, David A. Nichols
A new hierarchy of lasting gravitational-wave effects (the higher memory effects) was recently identified in asymptotically flat spacetimes, with the better-known displacement, spi…
Persistent gravitational wave observables: Nonlinearities in (non-)geodesic deviation
Alexander M. Grant
The usual gravitational wave memory effect can be understood as a change in the separation of two initially comoving observers due to a burst of gravitational waves. Over the past…
Higher Memory Effects in Numerical Simulations of Binary Black Hole Mergers
Alexander M. Grant, Keefe Mitman
Gravitational memory effects are predictions of general relativity that are characterized by an observable effect that persists after the passage of gravitational waves. In recent…
