“…TianQin is a space-based GW detector targeting GWs in the frequency band 10 −4 Hz∼ 1 Hz [61,62]. Among the promising scientific discovery potential of TianQin in many different directions [63][64][65][66][67][68][69][70][71][72], the detection of MBHBs is an outstanding one [73,74]. Motivated by the known result on LISA, it is likely that TianQin can also detect memory effect directly.…”

The gravitational wave memory effect is a direct prediction of general relativity. The presence of memory effect in gravitational wave signals not only provides the chance to test an important aspect of general relativity, but also represents a potentially non-negligible contribution to the waveform for certain gravitational wave events. In this paper, we study the prospect of directly detecting the gravitational wave memory effect with the planned space-based gravitational wave detector -TianQin. We also determine the region of parameter space in which the contribution of memory effect is significant to waveform modeling.

“…Finally, we have only considered circular orbits for SBBHs. Since the eccentricity can provide more astrophysical information [60,61,62,63,46], it is worth investigating whether the SBBH system with eccentricity will impact the estimation of the cosmological parameters [24].…”

“…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.

“…Gravitational waves offer an independent probe of fundamental physics [71][72][73] and in particular for the measurement of both the Hubble constant [74][75][76] and the gravitational constant [77,78] values, applicable for the coalescing compact binary systems that emitted them. Within 5 years of operation time, LISA is expected to measure the Hubble constant with an 1% accuracy [74] using dark and bright standard sirens which are self calibrated from gravitational considerations and independent of SnIa standard candle and standard ruler calibration [79]. This accuracy level is better than most present methods and has a comparable accuracy to that expected from other future space missions.…”

The Laser Interferometer Space Antenna (LISA) mission, scheduled for launch in the mid-2030s, is a gravitational wave observatory in space designed to detect sources emitting in the millihertz band. LISA is an ESA flagship mission, currently entering the Phase B development phase. It is expected to help us improve our understanding about our Universe by measuring gravitational wave sources of different types, with some of the sources being at very high redshifts z ∼ 20. On the 23rd of February 2022 we organized the 1 st LISA in Greece Workshop. This workshop aimed to inform the Greek scientific and tech industry community about the possibilities of participating in LISA science and LISA mission, with the support of the Hellenic Space Center (HSC). In this white paper, we summarize the outcome of the workshop, the most important aspect of it being the inclusion of 15 Greek researchers to the LISA Consortium, raising our total number to 22. At the same time, we present a road-map with the future steps and actions of the Greek Gravitational Wave community with respect to the future LISA mission.https://indico.physics.auth.gr/event/11/ a. The shape and organization of this document, have been inspired by the work of our Canadian Colleagues.
