dc.description.abstract | The assumptions of large-scale homogeneity and isotropy underly the familiar Friedmann-Lemaître-
Robertson-Walker (FLRW) metric that appears to be an accurate description of our Universe. In this
paper, we propose a new strategy of testing the validity of the FLRW metric, based on the galactic-scale
lensing systems where strongly lensed gravitational waves and their electromagnetic counterparts
can be simultaneously detected. Each strong lensing system creates opportunity to infer the curvature
parameter of the Universe. Consequently, combined analysis of many such systems will provide a
model-independent tool to test the validity of the FLRW metric. Our study demonstrates that the thirdgeneration ground based GW detectors, like the Einstein Telescope (ET) and space-based detectors, like the Big Bang Observer (BBO), are promising concerning determination of the curvature parameter or possible detection of deviation from the FLRW metric. Such accurate measurements of the FLRW metric can become a milestone in precision GW cosmology. | pl_PL |
