A Delayed Multi-channel Progenitor for Apparently Nonrepeating Fast Radio Bursts
Zhao-Wei Du, Xi-Long Fan, Yi-Xiao Li
Fast radio bursts (FRBs) are millisecond-duration radio flashes of unknown origin, observationally classified into repeating and apparently nonrepeating (one-off) populations. In t…

We investigate how gravitational wave (GW) observations can probe the internal physics of neutron stars by extending the Tolman-Oppenheimer-Volkoff framework to include pressure an…
Considering lensing effect on gravitational wave signals from black holes in mass gap
Qiyuan Yang, Zhi-Qiang You, Xilong Fan
The pair-instability supernova (PISN) mechanism predicts a mass gap in the black hole population, where no stellar-origin black holes are expected to form. However, several binary…
The diverse morphology of gravitational wave signals from merging neutron-star white-dwarf binaries
Shenghua Yu, Youjun Lu, C. Simon Jeffery +6
In sufficiently compact neutron star-white dwarf (NSWD) binary systems, orbital decay means the white dwarf eventually fills its shrinking Roche lobe, initiating a phase of mass tr…
The Hierarchical Merger Scenario for GW231123
Guo-Peng Li, Xi-Long Fan
GW231123 exhibits exceedingly massive components and high spins, which challenges the formation of first-generation (1G) black holes from stellar collapse and implies that this eve…
