R-process nucleosynthesis from magnetar giant flares in neutron star--white dwarf mergers: A unified picture for peculiar long gamma-ray bursts
Shu-Qing Zhong, Long Li, Le Zou +3
Peculiar long gamma-ray bursts (GRBs), exemplified by GRBs 211211A and 230307A, exhibit a long-duration multi-component prompt emission, an X-ray plateau in their afterglow, and a…
AT 2024wpp: the most luminous fast-evolving optical transient linked to the merger explosion of a black-hole binary
Jialian Liu, Bao Wang, Xiaofeng Wang +48
Fast blue optical transients (FBOTs) represent one of the most exotic astrophysical transients, exhibiting unusually strong emission across X-ray, optical, and radio wavelengths. T…
Hydrogen-poor Superluminous Supernovae with Bumpy Light Curves Powered by Precessing Magnetars
Biao Zhang, Long Li, Zi-Gao Dai +1
Recent observations and statistical studies have revealed that a significant fraction of hydrogen-poor superluminous supernovae (SLSNe-I) exhibit light curves that deviate from the…
Signature of Triaxially Precessing Magnetars in Gamma-ray Burst X-Ray Afterglows
Biao Zhang, Shu-Qing Zhong, Long Li +1
The X-ray afterglows of some gamma-ray bursts (GRBs) exhibit plateaus, which can be explained by the internal dissipation of a newborn millisecond magnetar wind. In the early phase…
Identifying the Origin of FRB-associated X-ray Bursts with X-ray Polarization
Shu-Qing Zhong, Long Li, Biao Zhang +1
The origin of extraordinary X-ray burst (XRB) associated with a fast radio burst (FRB) like FRB 20200428D is still unclear, though several models such as the emission of a trapped…
