Gravitational lensing of gravitational waves: universal characteristics of strongly lensed memory waveforms
Ruanjing Zhang, Zhi-Chao Zhao, Shaoqi Hou +3
The paper analyzes how strong gravitational lensing alters the gravitational‑wave memory signal, revealing universal, image‑type‑dependent waveform features that are independent of…
QPEs from Warped Disk Collisions with EMRIs: Brightness-Recurrence Diagram and Gravitational-Wave Follow-up
Bo-An Chen, Bei You, Giovanni Miniutti +11
Quasi-Periodic Eruptions (QPEs) display correlated long/short and strong/weak patterns that remain unexplained by existing flat-disk collision models. We propose that these feature…
Probing Primordial black holes with the distortion of Stochastic Gravitational Wave Background
Mingqi Sun, Kai Liao, Xi-Long Fan
The stochastic gravitational-wave background (SGWB), arising from the incoherent superposition of numerous compact binary coalescences, serves as a powerful probe of both astrophys…
Constraints on Compact Dark Matter Population from Micro-lensing Effect of Gravitational Wave for the third-generation gravitational Wave Detector
Xin-Yi Lin, Xi-Jing Wang, Huan Zhou +3
Since the pioneering detection of gravitational wave (GW) from a binary black hole merger by the LIGO-Virgo collaboration, GW has become a powerful probe for astrophysics and cosmo…
Lensed fast radio bursts as a probe of time-varying gravitational potential induced by wave dark matter
Ran Gao, Shuxun Tian, Zhengxiang Li +4
Ultralight bosonic wave dark matter (DM) is preponderantly contesting the conventional cold DM paradigm in predicting diverse and rich phenomena on small scales. For a DM halo made…
