“…Black hole (BH)-neutron star (NS) binary coalescences are among the prime sources of gravitational waves (GWs) for ground-based detectors, such as Advanced LIGO, Advanced Virgo, and KAGRA [1][2][3]. Gravitaional waves from BH-NS binaries will enable us to probe the supranuclear-density matter [4,5] and cosmological expansion [6] via the NS tidal effect even without electromagnetic (EM) observation.…”

The merger of black hole-neutron star binaries can eject substantial material with the mass ∼ 0.01-0.1M⊙ when the neutron star is disrupted prior to the merger. The ejecta shows significant anisotropy, and travels in a particular direction with the bulk velocity ∼ 0.2c. This is drastically different from the binary neutron star merger, for which ejecta is nearly isotropic. Anisotropic ejecta brings electromagnetic-counterpart diversity which is unique to black hole-neutron star binaries, such as viewing-angle dependence, polarization, and proper motion. The kick velocity of the black hole, gravitational-wave memory emission, and cosmic-ray acceleration are also discussed.

“…Their discovery would be a major breakthrough in our understanding of massive black hole formation [3,4], stellar-cluster evolution [5][6][7][8][9][10], and hyper/ultraluminous x-ray sources [11][12][13][14][15][16][17]. Coalescing intermediate mass black hole binaries (IMBHBs) are also the strongest candidate gravitational-wave (GW) sources accessible to ground-based interferometric detectors such as LIGO and Virgo [18,19].…”

and was sensitive to IMBHBs with a range up to ∼200 Mpc, averaged over the possible sky positions and inclinations of the binaries with respect to the line of sight. No significant candidate was found. Upper limits on the coalescence-rate density of nonspinning IMBHBs with total masses between 100 and 450 M ⊙ and mass ratios between 0.25 and 1 were placed by combining this analysis with an analogous search performed on data from the first LIGO-Virgo joint science run (November 2005-October 2007). The most stringent limit was set for systems consisting of two 88 M ⊙ black holes and is equal to 0.12 Mpc −3 Myr −1 at the 90% confidence level. This paper also presents the first estimate, for the case of an unmodeled analysis, of the impact on the search range of IMBHB spin configurations: the visible volume for IMBHBs with nonspinning components is roughly doubled for a population of IMBHBs with spins aligned with the binary's orbital angular momentum and uniformly distributed in the dimensionless spin parameter up to 0.8, whereas an analogous population with antialigned spins decreases the visible volume by ∼20%.

“…New experiments such as the advanced Laser Interferometry Gravitational-Wave Observatory (a-LIGO) [1], the advanced VIRGO interferometer [2], the Kamioka Wave Detector (KAGRA) [3], the space based mission DECIGO [4] or eLISA [5] will be able to test directly the existence of gravitational waves to improved levels. Gravity waves are also important probes for theories going beyond Einstein's General Relativity (GR) [6].…”

Abstract:We analyse the speed of gravitational waves in coupled Galileon models with an equation of state ω φ = −1 now and a ghost-free Minkowski limit. We find that the gravitational waves propagate much faster than the speed of light unless these models are small perturbations of cubic Galileons and the Galileon energy density is sub-dominant to a dominant cosmological constant. In this case, the binary pulsar bounds on the speed of gravitational waves can be satisfied and the equation of state can be close to -1 when the coupling to matter and the coefficient of the cubic term of the Galileon Lagrangian are related. This severely restricts the allowed cosmological behaviour of Galileon models and we are forced to conclude that Galileons with a stable Minkowski limit cannot account for the observed acceleration of the expansion of the universe on their own. Moreover any sub-dominant Galileon component of our universe must be dominated by the cubic term. For such models with gravitons propagating faster than the speed of light, the gravitons become potentially unstable and could decay into photon pairs. They could also emit photons by Cerenkov radiation. We show that the decay rate of such speedy gravitons into photons and the Cerenkov radiation are in fact negligible. Moreover the time delay between the gravitational signal and light emitted by explosive astrophysical events could serve as a confirmation that a modification of gravity acts on the largest scales of the Universe.
