Probing modified gravity with galaxy-cluster-lensed gravitational-wave time delays: impact of systematic effects
Strongly lensed gravitational waves provide exceptionally precise measurements of relative macroimage arrival times, making their time delays a promising time-domain probe of gravity on galaxy-cluster scales. This precision places stringent demands on the control of lensing systematic effects. We present a proof-of-con...
