Waveform models for the gravitational-wave memory effect: III. Phenomenological frequency-domain model for nonspinning binaries
Arwa Elhashash, David A. Nichols
We present a phenomenological frequency-domain model for the gravitational-wave (GW) memory signal from nonspinning binary-black-hole mergers on quasicircular orbits. We develop se…
Effects of the interaction of dark matter and neutron-star matter on extreme and intermediate mass-ratio inspirals
Benjamin A. Wade, Julian Heeck, David A. Nichols
Extreme and intermediate mass-ratio inspirals in a dense dark-matter distribution have the effects of the dark matter imprinted on the orbital dynamics of and the emitted gravitati…
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…
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…
Multi-messenger-Athena Synergy White Paper
L. Piro, M. Ahlers, A. Coleiro +30
In this paper we explore the scientific synergies between Athena and some of the key multi-messenger facilities that should be operative concurrently with Athena. These facilities…
Gravitational-wave memory effects in Brans-Dicke theory: Waveforms and effects in the post-Newtonian approximation
Shammi Tahura, David A. Nichols, Kent Yagi
Gravitational-wave (GW) memory effects produce permanent shifts in the GW strain and its time integrals after the passage of a burst of GWs. Their presence is closely tied to symme…
Detecting dark matter around black holes with gravitational waves: Effects of dark-matter dynamics on the gravitational waveform
Bradley J. Kavanagh, David A. Nichols, Gianfranco Bertone +1
A dark matter overdensity around a black hole may significantly alter the dynamics of the black hole's merger with another compact object. We consider here intermediate mass-ratio…
