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…
Hierarchical Test of Lorentz Invariance with Gamma-Ray Burst Spectral-Lag Measurements
Shen-Shi Du, Yi Gong, Jun-Jie Wei +4
Gamma-ray bursts (GRBs) are among the most potent probes of Lorentz invariance violation (LIV), offering direct constraints on the quantum gravity energy scale () based…
Is gamma-ray burst polarization from photosphere emission?
Yan-Zhi Meng, Shu-Qing Zhong, Jia-Hong Gu +2
Context: Despite more than half a century of research, the dominant radiation mechanism of gamma-ray burst (GRB) prompt emission remains unsolved. Some progress has been made throu…
Gravitational lensing of the wormhole in the Eddington-inspired Born-Infeld spacetime with a cosmic string
Xin-Fei Li, Lei-Hua Liu, Yan-Zhi Meng +2
In this work we study gravitational lensing of the wormhole in the Eddington-inspired Born-Infeld (EiBI) spacetime that incorporates with a cosmic string. It was found that the pre…
Gravitational waves associated with the r-mode instability from neutron star-white dwarf mergers
Shu-Qing Zhong, Yan-Zhi Meng, Jia-Hong Gu
Neutron star-white dwarf (NS-WD) binaries evolve into either ultra-compact X-ray binaries undergoing stable mass transfer or direct mergers by unstable mass transfer. While much at…
