Prospect of Measuring the Cosmic Dipole by Associating Strongly Lensed Gravitational Waves with Galaxy Surveys
Anson Chen, Jun Zhang
The paper studies how strongly lensed gravitational‑wave events, combined with galaxy redshift data, can be used to measure the cosmic dipole and test its consistency with CMB and…
Searching for Extra Dimensions with Gravitational Waves: Dark-Siren Constraints from GWTC-4
Anson Chen, Jun Zhang
Higher-dimensional theories of gravity predict that gravitational waves (GWs) can propagate into extra spatial dimensions, leading to modified amplitude damping over cosmological d…
Forecasting Constraints on Cosmology and Modified Gravitational-wave Propagation by Combining Strongly Lensed Gravitational Waves and Galaxy Surveys
Anson Chen, Jun Zhang
Gravitational lensing of gravitational wave (GW) will become the next frontier in studying cosmology and gravity. While time-delay cosmography using quadruply lensed GW events asso…
Measuring the cosmic dipole with golden dark sirens in the era of next-generation ground-based gravitational wave detectors
Anson Chen
The tensions between cosmological parameter measurements from the early-universe and the late-universe datasets offer an exciting opportunity to explore new physics, if not account…
Invariance transformations in wave-optics lensing: implications for gravitational-wave astrophysics and cosmology
Anson Chen, Paolo Cremonese, Jose MarÃa Ezquiaga +1
Gravitational lensing offers unique opportunities to learn about the astrophysical origin of distant sources, the abundance of intervening objects acting as lenses, and gravity and…
