“…Let us first consider the spherically symmetric ( = 0) case. In general, the perturbation to the metric due to the effect of a small spherically symmetric accretion flow can be expressed as [82,83] ds 2 = −F e 2δλ(v,r) dv 2 + 2e δλ(v,r) dvdr + r 2 dΩ 2 , (4) in terms of the perturbation of the metric δλ(v, r) and…”

The deformability of a compact object under the presence of a tidal perturbation is encoded in the tidal Love numbers (TLNs), which vanish for isolated black holes in vacuum. We show that the TLNs of black holes surrounded by matter fields do not vanish and can be used to probe the environment around binary black holes. In particular, we compute the TLNs for the case of a black hole surrounded by a scalar condensate under the presence of scalar and vector tidal perturbations, finding a strong power-law behavior of the TLN in terms of the mass of the scalar field. Using this result as a proxy for gravitational tidal perturbations, we show that future gravitational-wave detectors like the Einstein Telescope and LISA can impose stringent constraints on the mass of ultralight bosons that condensate around black holes due to accretion or superradiance. Interestingly, LISA could measure the tidal deformability of dressed black holes across the range from stellar-mass (≈ 10 2 M ) to supermassive (≈ 10 7 M ) objects, providing a measurement of the mass of ultralight bosons in the range (10 −17 − 10 −13 ) eV with less than 10% accuracy, thus filling the gap between other superradiance-driven constraints coming from terrestrial and space interferometers. Altogether, LISA and Einstein Telescope can probe tidal effects from dressed black holes in the combined mass range (10 −17 − 10 −11 ) eV.

“…The interaction of a black hole binary and a scalar field environment in the early-inspiral regime, where the separation is large and almost constant with time, has been explored via effective field theory [110,111], weak field approximations [112][113][114][115][116][117][118][119][120]; perturbative schemes [100,102,[121][122][123][124][125][126], and N-body and mesh numerical simulations [29,80,[127][128][129]. The effect of a non-vacuum environment on the post-merger "ringdown" regime, particularly the effect on the frequencies of the characteristic quasi-normal modes has also been explored by a number of authors [130][131][132][133][134]. To model the highly relativistic and dynamical merger one must use full numerical relativity.…”

Black hole merger simulations in wave dark matter environments

The interaction of binary black hole mergers with their environments can be studied using numerical relativity simulations. These start only a short finite time before merger, at which point appropriate initial conditions must be imposed. A key task is therefore to identify the configuration that is appropriate for the binary and its environment at this stage of the evolution. In this work we study the behaviour of wave dark matter around equal mass black hole binaries, finding that there is a preferred, quasi-stationary profile that persists and grows over multiple orbits, in contrast to heavier mass dark matter where any overdensity tends to be dispersed by the binary motion. Whilst different initial configurations converge to the preferred quasi-stationary one after several orbits, unwanted transient oscillations are generated in the process, which may impact on the signal in short simulation runs. We also point out that naively superimposing the matter onto a circular binary results in artificially eccentric orbits due to the matter backreaction, which is an effect of the initial conditions and not a signature of dark matter. We discuss the further work required so that comparison of waveforms obtained with environments to vacuum cases can be done in a meaningful way.

“…According to his paper for a set of complex-valued frequencies, it is possible to consider outgoing and incoming waves in the spatial infinity and in the vicinity of the event horizon, respectively. Soon afterward these frequencies are called the quasinormal (Q-N) modes [9] and have been extensively examined [10][11][12][13].…”

Based on the minimum measurable momentum concepts associated with the quantum gravity effects acting on the large-scale dynamics of the universe. We use the new extended uncertainty principle (EUP) to study the Hawking temperature and black hole evaporation. The results show the new EUP quantum correction may shorten the lifetime of the massive black hole. To verify the new EUP on the black hole stability, we further investigate the quasinormal frequencies in terms of the 3rd order WKB approximation. The corrected Schwarzschild black hole is still stable under the uncertainty parameter 𝛼 is considered to be a small value. Furthermore, we analyze the transmission and reflection coefficients and discuss the absorption cross section with graphical methods in detail. It shows that the uncertainty parameter 𝛼 has a non-negligible effect on the scattering amplitudes of the corrected black hole.
