“…SOB-HBs can however reach this level of accuracy only if the detection rate will fall in the optimistic range, which will crucially depend on the yet uncertain sensitivity that LISA will be able to achieve at high frequencies (Moore et al 2019). Note also that an "archival" search for SOBHBs will be possible: detecting the black hole merger with the third generation of ground-based GW detectors and then search those sources in the (archival) LISA data with the reduced prior (Ewing et al 2021). On the other hand, EMRIs rely on the LISA sensitivity around the mHz (middle-band) which is guaranteed to be at the level considered in our analysis (Amaro-Seoane et al 2017), if not better.…”

The Laser Interferometer Space Antenna (LISA) will open the mHz frequency window of the gravitational wave (GW) landscape. Among all the new GW sources expected to emit in this frequency band, extreme mass-ratio inspirals (EMRIs) constitute a unique laboratory for astrophysics and fundamental physics. Here we show that EMRIs can also be used to extract relevant cosmological information, complementary to both electromagnetic (EM) and other GW observations. By using the loudest EMRIs (SNR>100) detected by LISA as dark standard sirens, statistically matching their sky localisation region with mock galaxy catalogs, we find that constraints on H0 can reach ∼1.1 per cent (∼3.6 per cent) accuracy, at the 90 per cent credible level, in our best (worst) case scenario. By considering a dynamical dark energy (DE) cosmological model, with ΛCDM parameters fixed by other observations, we further show that in our best (worst) case scenario ∼5.9 per cent (∼12.3 per cent) relative uncertainties at the 90 per cent credible level can be obtained on w0, the DE equation of state parameter. Besides being relevant in their own right, EMRI measurements will be affected by different systematics compared to both EM and ground-based GW observations. Cross validation with complementary cosmological measurements will therefore be of paramount importance, especially if convincing evidence of physics beyond ΛCDM emerges from future observations.

“…It has been proposed that future ground-based GW detectors can detect SBBH mergers, and trigger a targeted search in space-borne GW detector archive data. Such archival search will be performed in a shrunk parameter space, gaining the potential of further lowering the detection threshold for SNR 5 [99,100]. In such a case, up to ∼ 120 sources could be observed with TianQin.…”

“…These correlations may either enhance or reduce the constraining power of future detectors. Finally, it will be interesting to understand how to best optimize the 3G detector network and to investigate the potential of multiband events [180][181][182][183][184][185][186] to better assess the (primordial or astrophysical) nature of the observed merging events.

A population of primordial black holes formed in the early Universe could contribute to at least a fraction of the black-hole merger events detectable by current and future gravitational-wave interferometers. With the ever-increasing number of detections, an important open problem is how to discriminate whether a given event is of primordial or astrophysical origin. We systematically present a comprehensive and interconnected list of discriminators that would allow us to rule out, or potentially claim, the primordial origin of a binary by measuring different parameters, including redshift, masses, spins, eccentricity, and tidal deformability. We estimate how accurately future detectors (such as the Einstein Telescope and LISA) could measure these quantities, and we quantify the constraining power of each discriminator for current interferometers. We apply this strategy to the GWTC-3 catalog of compact binary mergers. We show that current measurement uncertainties do not allow us to draw solid conclusions on the primordial origin of individual events, but this may become possible with next-generation ground-based detectors.
