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…

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…
