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…
Identifying the poynting-flux-dominated outflow of Fermi GRBs with non-thermal spectrum and its energy-resolved light curve fitting
Xue-Zhao Chang, HouJun Lü, Zhao-Wei Du +2
The jet compositions of gamma-ray bursts (GRBs) are very important to understand the energy dissipation and radiation mechanisms, but it remains an open question in GRB physics. In…
Neutron Star-White Dwarf Merger as One Possible Optional Source of Kilonova-like Emission: Implications for GRB 211211A
Xiao-Xuan Liu, Hou-Jun Lü, Qiu-Hong Chen +2
Long-duration GRB 211211A, which lacked an associated supernova at such a low redshift , but was associated with a possible kilonova emission, has attracted great attentio…
How to identify the object with mass range of in the merger of compact star systems
ZhaoWei Du, HouJun Lü, Xiaoxuan Liu +2
High-frequency gravitational-wave (GW) radiation has been detected by LIGO-Virgo-KAGRA in the merger of compact stars. However, two GW events, GW190814 and GW200210, the mass of on…
The progenitor and central engine of a peculiar GRB 230307A
ZhaoWei Du, HouJun Lü, Yong Yuan +2
Recently, a lack of supernova-associated long-duration gamma-ray burst (GRB 230307A) at such a low redshift , but associated with a possible kilonova emission, has attract…
The Jet Composition of GRB 230307A: Poynting-Flux-Dominated Outflow?
Zhao-Wei Du, HouJun Lü, Xiaoxuan Liu +1
The jet composition of GRB plays an important role in understanding the energy dissipation and radiation mechanisms in GRB physics, but it is poorly constrained from the observatio…
