abstract

The cross-correlation of gravitational wave strain with upcoming galaxy surveys probe theories of gravity in a new way. This method enables testing the theory of gravity by combining the effects from both gravitational lensing of gravitational waves and the propagation of gravitational waves in spacetime. We find that within 10 years, the combination of the Advanced-LIGO and VIRGO detector networks with planned galaxy surveys should detect weak gravitational lensing of gravitational waves in the low redshift Universe ($z<0.5$). With the next generation gravitational wave experiments such as Voyager, LISA, Cosmic-Explorer and Einstein Telescope, we can extend this test of the theory of gravity to larger redshifts by exploiting the synergies between electromagnetic wave and gravitational wave probes.

  1. Forecasting Constraints on Cosmology and Modified Gravitational-wave Propagation by Combining Strongly Lensed Gravitational Waves and Galaxy Surveys

    astro-ph.CO 2026-01 conditional novelty 6.0 of 10

    Simulated doubly lensed gravitational-wave events matched to galaxy surveys give a forecasted H0 precision of 0.42% with next-generation detectors.

  2. Can Eccentric Binary Black Hole Signals Mimic Gravitational-Wave Microlensing?

    gr-qc 2025-12 conditional novelty 6.0 of 10

    Eccentric BBH signals can masquerade as wave-optics microlensing in quasicircular analyses, but eccentric recovery templates break the degeneracy.

  3. Modeling Gravitational Wave Bias from 3D Power Spectra of Spectroscopic Surveys

    astro-ph.GA 2025-06 conditional novelty 6.0 of 10

    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...

  4. Weak deflection angle of charged signal in magnetic fields

    gr-qc 2025-01 conditional novelty 6.0 of 10

    Weak deflection of charged signals in magnetized black hole spacetimes can be split into gravitational and electromagnetic parts, with magnetic dipole effects entering one order higher than electrostatic effects.

  5. Multi-Messenger Cosmology: A Route to Accurate Inference of Dark Energy Beyond CPL Parametrization from XG Detectors

    astro-ph.CO 2024-12 conditional novelty 5.0 of 10

    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.
