One Merger, Three Bands: Multiband Detection Rates and Parameter Estimation of Stellar-mass Binary Black Hole Coalescences from Millihertz to Kilohertz
Anson Chen, Jun Zhang
Stellar-mass binary black holes sweep through the millihertz, decihertz, and kilohertz gravitational-wave bands before merger, making them prime targets for multiband observations.…
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…
Prospect of Measuring the Cosmic Dipole by Associating Strongly Lensed Gravitational Waves with Galaxy Surveys
Anson Chen, Jun Zhang
The cosmic dipole observed in the cosmic microwave background (CMB) is traditionally interpreted as being caused by the observer's motion relative to the background. However, tensi…
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…
Probing Massive Fields with Multi-Band Gravitational-Wave Observations
Mu-Chun Chen, Hao-Yang Liu, Qi-Yan Zhang +1
We investigate the prospect of probing massive fields and testing gravitational theories with multiband observations of gravitational waves emitted from coalescing compact binaries…
Superradiant clouds may be relevant for close compact object binaries
Ao Guo, Jun Zhang, Huan Yang
Bosonic fields (within suitable mass range) may be collectively generated by rotating black holes through the black hole superradiance process. The resulting black hole is surround…
