Gravitational waves can provide an accurate measurement of the luminosity distance to the source, but cannot provide the source redshift unless the degeneracy between mass and redshift can be broken. This makes it essential to infer the redshift of the source independently to measure the expansion history of the Universe. We show that by exploiting the clustering scale of the gravitational wave sources with galaxies of known redshift, we can infer the expansion history from redshift unknown gravitational wave sources. By using gravitational wave sources of unknown redshift that are detectable from the network of gravitational wave detectors with Advanced LIGO design sensitivity, we will be able to obtain accurate and precise measurements of the local Hubble constant, the expansion history of the universe, and the gravitational wave bias parameter, which captures the distribution of gravitational wave sources with respect to the redshift tracer distribution. While we showcase its application to low redshift gravitational waves, this technique will be applicable also to the high redshift gravitational wave sources detectable from Laser Interferometer Space Antenna (LISA), Cosmic Explorer (CE), and Einstein Telescope (ET). Moreover, this method will also be applicable to samples of supernovae and fast radio bursts with unknown or photometric redshifts.

Skipping the rungs! Calibrating distance indicators through their clustering with galaxies
Fisher forecasts show angular cross-correlations between distance indicators and galaxy catalogs can constrain a constant calibration offset to ~0.05 mag and H0 to ~1.81 km/s/Mpc with future LSST+DESI data.

Modeling Gravitational Wave Bias from 3D Power Spectra of Spectroscopic Surveys
Using mock gravitational wave catalogs built from the SDSS DR7 galaxy survey, the clustering bias of GW sources is most sensitive to host stellar mass, secondarily to star formation rate, and nearly insensitive to met...

A Bright Future? Prospects for Cosmological Tests of GR with Multimessenger Gravitational Wave Events
Simulated bright siren events show LVK-era detections will not competitively constrain Horndeski gravity parameters, while one year of Einstein Telescope observations could detect αM ≠ 0 at over 3σ.

The Gravitational Wave Bias Parameter from Angular Power Spectra: Bridging Between Galaxies and Binary Black Holes
The gravitational wave bias of mock binary black holes increases with the pivot mass of the assumed host galaxy mass selection, and can exceed the galaxy bias by up to about 30 percent only for steep host probability slopes.

Multi-Messenger Cosmology: A Route to Accurate Inference of Dark Energy Beyond CPL Parametrization from XG Detectors
A simulation forecast claims CE+ET bright standard sirens can measure dark energy EoS parameters with sigma(w0)=0.010, sigma(wa)=0.049, sigma(wb)=0.072, better than other planned probes.

A robust cosmic standard ruler from the cross-correlations of galaxies and dark sirens
Cross-correlating dark siren distances with galaxy redshifts, the 'Peak Sirens' method traces the Hubble diagram, forecasting 7% H0 precision for LVK O5 and sub-percent for next-generation detectors.
