Intermediate mass-ratio inspirals in a dense dark-matter environment: Effects of the initial dark-matter distribution
Benjamin A. Wade, David A. Nichols
Recent work has shown the possibility of detecting dense dark-matter distributions surrounding intermediate or extreme mass-ratio inspirals through gravitational waves using LISA.…
Gravitational-wave memory effects in the Damour-Esposito-Farèse extension of Brans-Dicke theory
Shammi Tahura, David A. Nichols, Kent Yagi
Gravitational-wave memory effects are lasting changes in the strain and its time integrals. They can be computed in asymptotically flat spacetimes using the conservation and evolut…
Waveform models for the gravitational-wave memory effect: Extreme mass-ratio limit and final memory offset
Arwa Elhashash, David A. Nichols
The gravitational-wave (GW) memory effect is a strong-field relativistic phenomenon that is associated with a persistent change in the GW strain after the passage of a GW. The nonl…
Probing dark-matter effects with gravitational waves using the parameterized post-Einsteinian framework
Eileen Wilcox, David Nichols, Kent Yagi
A massive black hole can develop a dark-matter overdensity, and the dark matter changes the evolution of a stellar-mass compact object inspiraling around the massive black hole thr…
