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…
Illuminating the dark universe in the multi-messenger era
Philippe Brax, Anne-Christine Davis, Md Riajul Haque +8
The precision era of multi-messenger astronomy, together with modern astrophysical, cosmological, and gravitational wave observations, increasingly points toward the existence of a…
Common Envelope Evolution of Ultralight Boson Clouds
Ao Guo, Qi-Yan Zhang, Huan Yang +1
Ultralight bosons can be excited around spinning black holes via black hole superradiance. These boson clouds may play an important role in the orbital evolution of binary black ho…
Scalar-Gauss-Bonnet gravity: Infrared causality and detectability of GW observations
Wen-Kai Nie, Lin-Tao Tan, Jun Zhang +1
We investigate time delays of wave scatterings around black hole backgrounds in scalar-tensor effective field theories of gravity. The scalar-Gauss-Bonnet (sGB) couplings, being co…
