Abstract
The cross-correlation of gravitational wave events with upcoming galaxy
surveys probe theories of gravity in a fundamentally new way, with the
potential to reveal clues as to the nature of dark energy and dark matter. We
find that within 10 years, the combination of the Advanced-LIGO and VIRGO
detector network with planned galaxy surveys can 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 the range of this probe
up to a redshift of $z20$. This new probe will test the theory of gravity
using both gravitational wave propagation through spacetime and also the effect
of cosmic structures on gravitational waves, opening up a new observational
window for cosmology and fundamental physics.
