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…
Fully nonlinear transformations of the Weyl-Bondi-Metzner-Sachs asymptotic symmetry group
Eanna E. Flanagan, David A. Nichols
The asymptotic symmetry group of general relativity in asymptotically flat spacetimes can be extended from the Bondi-Metzner-Sachs (BMS) group to the generalized BMS (GMBS) group s…
Secondary accretion of dark matter in intermediate mass-ratio inspirals: Dark-matter dynamics and gravitational-wave phase
David A. Nichols, Benjamin A. Wade, Alexander M. Grant
When particle dark matter is bound gravitationally around a massive black hole in sufficiently high densities, the dark matter will affect the rate of inspiral of a secondary compa…
