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…

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…
