“…In the case of LISA [38], the main contribution of the total errors on d L at high redshift comes from the weak lensing part (24), which will decrease by a factor of 2 when we account for the merger and ringdown. The peculiar velocity error [38] is given by…”

“…With the identification of the associated electromagnetic (EM) counterpart, the redshift can also be determined. Apart from the coalescing binaries involving neutron stars, the massive black hole binaries (MBHBs) from 10 4 to 10 7 M are also expected to produce a detectable EM counterpart, because they are supposed to merge in a gas-rich environment and within the laser interferometer space antenna (LISA) frequency band [37,38]. In addition, the MBHB standard siren will probe the cosmic expansion at distances up to z ∼ 15 that SNIa cannot reach.…”

The gravitational wave (GW) as a standard siren directly determines the luminosity distance from the gravitational waveform without reference to the specific cosmological model, of which the redshift can be obtained separately by means of the electromagnetic counterpart like GW events from binary neutron stars and massive black hole binaries (MBHBs). To see to what extent the standard siren can reproduce the presumed dipole anisotropy written in the simulated data of standard siren events from typical configurations of GW detectors, we find that (1) for the Laser Interferometer Space Antenna with different MBHB models during five-year observations, the cosmic isotropy can be ruled out at 3σ confidence level (C.L.) and the dipole direction can be constrained roughly around 20% at 2σ C.L., as long as the dipole amplitude is larger than 0.03, 0.06 and 0.025 for MBHB models Q3d, pop III and Q3nod with increasing constraining ability, respectively; (2) for Einstein Telescope with no less than 200 standard siren events, the cosmic isotropy can be ruled out at 3σ C.L. if the dipole amplitude is larger than 0.06, and the dipole direction can be constrained within 20% at 3σ C.L. if the dipole amplitude is near 0.1; (3) for the Deci-Hertz Interferometer Gravitational wave Observatory with no less than 100 standard siren events, the cosmic isotropy can be ruled out at 3σ C.L. for dipole amplitude larger than 0.03 , and the dipole direction can even be constrained within 10% at 3σ C.L. if the dipole amplitude is larger than 0.07. Our work manifests the promising perspective of the constraint ability on the cosmic anisotropy from the standard siren approach.

“…Indeed, the luminosity distance to GW150914 was estimated to be 410 +160 −180 Mpc using this technique [1]. With the redshift information from independent observations of an electromagnetic (EM) counterpart, one can directly constrain the absolute distance-redshift relation, and hence obtains constraints on cosmological parameters including the Hubble constant and dark energy parameters [5][6][7][8][9][10][11][12][13][14][15][16].…”

Measuring the distance-redshift relation with the cross-correlation of gravitational wave standard sirens and galaxies

Gravitational waves from inspiraling compact binaries are known to be an excellent absolute distance indicator, yet it is unclear whether electromagnetic counterparts of these events are securely identified for measuring their redshifts, especially in the case of black hole-black hole mergers such as the one recently observed with the Advanced LIGO. We propose to use the cross-correlation between spatial distributions of gravitational wave sources and galaxies with known redshifts as an alternative means of constraining the distance-redshift relation from gravitational waves. In our analysis, we explicitly include the modulation of the distribution of gravitational wave sources due to weak gravitational lensing. We show that the cross-correlation analysis in next-generation observations will be able to tightly constrain the relation between the absolute distance and the redshift, and therefore constrain the Hubble constant as well as dark energy parameters.

“…Our objective, however, is to explore the mechanisms that may potentially drive EM signals directly associated with the strongest GW emissions within hours of the merger event itself. Such emissions could be crucial, for example, in LISA-based redshift-distance studies [29].…”

Binary black hole (BBH) mergers provide a prime source for current and future interferometric gravitational wave observatories. Massive BBH mergers may often take place in plasma-rich environments, leading to the exciting possibility of a concurrent electromagnetic (EM) signal observable by traditional astronomical facilities. However, many critical questions about the generation of such counterparts remain unanswered. We explore mechanisms that may drive EM counterparts with magnetohydrodynamic simulations treating a range of scenarios involving equal-mass black-hole binaries immersed in an initially homogeneous fluid with uniform, orbitally aligned magnetic fields. We find that the time development of Poynting luminosity, which may drive jetlike emissions, is relatively insensitive to aspects of the initial configuration. In particular, over a significant range of initial values, the central magnetic field strength is effectively regulated by the gas flow to yield a Poynting luminosity of 10 45 − 10 46 ρ -13 M 8 2 erg s −1 , with BBH mass scaled to M 8 ≡ M=ð10 8 M ⊙ Þ and ambient density ρ -13 ≡ ρ=ð10 −13 g cm −3 Þ. We also calculate the direct plasma synchrotron emissions processed through geodesic ray-tracing. Despite lensing effects and dynamics, we find the observed synchrotron flux varies little leading up to merger.
