“…However, others [12] states the corrections of DM halos to the GW signal or environment effects are negligible. Later, the related studies [13][14][15][16][17] continue and support the claim that phases of GW can be modified to have impacts on future space-borne GW experiments. Extensions to different DM candidates [18][19][20][21] and discussions of backreaction [16,22,23] have also been explored.…”

The exact properties of dark matter remain largely unknown despite of the accumulating evidence. If dark matter is composed of weakly-interacting massive particles, it would be accreted by the black hole in galactic center and forms a dense cuspy spike. Dynamical friction from such a spike may have observable effects in a binary system. We consider extreme-mass-ratio inspiral (EMRI) binaries consisting of massive black holes harbored in dark matter spikes and stellar mass objects in elliptic orbits. We find the gravitational-wave waveforms in frequency domain can be significantly modified.In particular, we show dark matter can suppress the characteristic strain of gravitational wave at low frequency but enhance it at higher domain. These effects are more dramatic as the dark matter density increases. The results indicate that the signal-to-noise ratio of EMRIs could be strongly reduced around 10 −3 ∼ 0.3 Hz but enhanced around 1.0 Hz with a higher sensitivity, which could be probed via future space-borne GW detectors, LISA and TAIJI. The findings would have important impacts on the detection and parameter inference of EMRIs.

“…Besides gravitational waves emitted directly by the cloud, if the black hole-boson cloud system is part of a binary, a wealth of other effects can occur that lead to very distinct and potentially detectable signatures in the gravitational waves emitted by the coalescing binary [82]. Those include signatures induced by the tidal field of the companion object, such as level mixing, ionization, tidal resonances and tidal disruption [82][83][84][85][86][87][88], non-vanishing tidal Love numbers [82,89], signatures induced by the multipolar structure of the boson cloud [82,90] and effects such as the accretion of the cloud by the companion object, dynamical friction, and the impact caused by the self-gravity of the cloud itself [88,[91][92][93][94][95][96]. All those effects taken together can contribute to a potentially observable change in the gravitational signal emitted by a binary black hole, if one or both black holes in the binary are surrounded by a boson cloud.…”

Exploring dark matter via observations of extreme astrophysical environmentsdefined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well as supernovae and compact object merger events -has been a major field of growth since the last Snowmass process. Theoretical work has highlighted the utility of current and near-future observatories to constrain novel dark matter parameter space across the full mass range. This includes gravitational wave instruments and observatories spanning the electromagnetic spectrum, from radio to gamma-rays. While recent searches already provide leading sensitivity to various dark matter models, this work also highlights the need for theoretical astrophysics research to better constrain the properties of these extreme astrophysical systems. The unique potential of these search signatures to probe dark matter adds motivation to proposed next-generation astronomical and gravitational wave instruments.

“…Because the underlying phenomenon of black hole superradiance only relies on gravitational interactions, it facilitates searches for new particles independently from their specific coupling to the standard model and thus complements traditional collider physics or direct detection experiments. The single black hole scenario has been studied extensively, and there are first computations of binary black-hole systems in the weak-field regime [253][254][255], for extreme mass ratio inspirals [256][257][258] and in the fully nonlinear regime modeling the last orbit before merger, the merger and ringdown [259]. How these light fields impact the nonlinear dynamics of the late inspiral and coalescence of black-hole binaries endowed with scalar condensates and what its observational signatures are remain open questions.…”

The next generation of gravitational-wave detectors, conceived to begin operations in the 2030s, will probe fundamental physics with exquisite sensitivity. These observations will measure the equation of state of dense nuclear matter in the most extreme environments in the universe, reveal with exquisite fidelity the nonlinear dynamics of warped spacetime, put general relativity to the strictest test, and perhaps use black holes as cosmic particle detectors. Achieving each of these goals will require a new generation of numerical relativity simulations that will run at scale on the supercomputers of the 2030s to achieve the necessary accuracy, which far exceeds the capabilities of numerical relativity and high-performance computing infrastructures available today. Contents 1 Motivation 2 Gravitational waveform modeling 3 Nuclear physics and neutron stars 4 Modeling high-precision gravitational-wave observations 5 Testing gravity in the nonlinear regime 6 Black holes as cosmic particle detectors
