“…This means that our results in Table 1 might be optimistic. To eliminate such a selection bias, several works have derived a correction term into the Bayesian framework [18,23,49,50]. In addition, the incompleteness of the galaxy catalog can be compensated by the GWtriggered deeper field galaxy surveys [51,52,53].…”

“…Their results constrained H 0 to be H 0 = 77 +37 −18 km s −1 Mpc −1 . Recent studies have explored the prospects of the dark-siren cosmology using Bayesian framework with observations [4,20] as well as simulated data [21,22,23,24]. Extending earlier methods and criteria, in this work we discuss the constraints on the cosmological parameters with space-borne decihertz GW detectors.…”

Gravitational waves (GWs) originated from mergers of stellar-mass binary black holes (SBBHs) are considered as dark sirens in cosmology since they usually do not have electromagnetic counterparts. In order to study cosmos with these events, we not only need the luminosity distances extracted from GW signals, but also require the redshift information of sources via, say, matching GW sky localization with galaxy catalogs. Based on such a methodology, we explore how well decihertz GW detectors, DO-Optimal and DECIGO, can constrain cosmological parameters. Using Monte-Carlo simulated dark sirens, we find that DO-Optimal can constrain the Hubble parameter to σ H0 /H 0 0.2% when estimating H 0 alone, while DECIGO performs better by a factor of 6 with σ H0 /H 0 0.03%. Such a good precision of H 0 will shed light on the H 0 tension. For multiple-parameter estimation, DECIGO can still reach a level of σ H0 /H 0 5%. The reason why decihertz detectors perform well is explained by their large numbers of SBBH GW events with good distance and angular resolution.

“…In the presence of an electromagnetic (EM) counterpart, the redshift can be obtained identifying and observing the host galaxy with EM facilities; this information can then be used to construct the d L −z diagram and constrain cosmological parameters [17,26] (see also [27][28][29] for groundbased detectors). If no EM counterpart is present, statistical methods can be employed to infer the cosmological parameters, if enough GW sources are available [30][31][32][33][34][35][36].…”

In the next decade, the Laser Interferometer Space Antenna (LISA) will detect the coalescence of massive black hole binaries (MBHBs) in the range [10 4 , 10 8 ] M , up to z ∼ 10. Their gravitational wave (GW) signal is expected to be accompanied by an electromagnetic counterpart (EMcp), generated by the gas accreting on the binary or on the remnant BH. In this work, we present the number and characteristics (such as redshift and mass distribution, apparent magnitudes or fluxes) of EMcps detectable jointly by LISA and some representative EM telescopes. We combine state-of-the-art astrophysical models for the galaxies formation and evolution to build the MBHBs catalogues, with Bayesian tools to estimate the binary sky position uncertainty from the GW signal. Exploiting additional information from the astrophysical models, such as the amount of accreted gas and the BH spins, we evaluate the expected EM emission in the soft X-ray, optical and radio bands. Overall, we predict between 7 and 21 EMcps in 4 yrs of joint observations by LISA and the considered EM facilities, depending on the astrophysical model. We also explore the impact of the hydrogen and dust obscuration of the optical and X-ray emissions, as well as of the collimation of the radio emission: these effects reduce the number to EMcps to 2 or 3, depending on the astrophysical model, again in 4 yrs of observations. Most of the EMcps are characterised by faint EM emission, challenging the observational capabilities of future telescopes. Finally, we also find that systems with multi-modal sky position posterior distributions represent only a minority of cases and do not affect significantly the number of EMcps.
