Identification of Lensed Gravitational-Wave Beat Patterns by LISA
Hengyu Wu, Tonghua Liu, Kai Liao
Strong lensing of massive black hole binaries can produce multiple gravitational-wave images with different magnifications and arrival times. LISA signals remain in band for months…

Mock Catalogs of Strongly Lensed Gravitational Waves via a Halo Model Approach with Space-borne Detectors
Mingqi Sun, Kai Liao, Youkai Li +6
Future space-borne gravitational-wave (GW) detectors, such as LISA and DECIGO, are expected to detect a large number of GW events, a fraction of which may be strongly lensed by int…

Determination of cosmic curvature independent of the sound horizon and using BOSS/eBOSS and DESI DR1 BAO observations
Tonghua Liu, Shengjia Wang, Hengyu Wu +1
We present an improved model-independent method for determining the cosmic curvature using the observations of Baryon Acoustic Oscillations (BAOs) and the Hubble parameter. The pur…
