A past capture event at Sagittarius A* inferred from the fluorescent X-ray emission of Sagittarius B clouds
Yun-Wei Yu, K. S. Cheng, D. O. Chernyshov +1
The fluorescent X-ray emission from neutral iron in the molecular clouds (Sgr B) indicates that the clouds are being irradiated by an external X-ray source. The source is probably…
The termination shock of a magnetar wind: a possible origin of gamma-ray burst X-ray afterglow emission
Z. Mao, Yun-Wei Yu, Z. G. Dai +2
Context: Swift observations suggest that the X-ray afterglow emission of some gamma-ray bursts (GRB) may have internal origins, and the conventional external shock (ES) cannot be t…
High Redshift Gamma-Ray Bursts: Observational Signatures of Superconducting Cosmic Strings?
K. S. Cheng, Yun-Wei Yu, T. Harko
The high-redshift gamma-ray bursts (GRBs), GRBs 080913 and 090423, challenge the conventional GRB progenitor models by their short durations, typical for short GRBs, and their high…
The role of newly born magnetars in gamma-ray burst X-ray afterglow emission: Energy injection and internal emission
Yun-Wei Yu, K. S. Cheng, Xiao-Feng Cao
Swift observations suggest that the central compact objects of some gamma-ray bursts (GRBs) could be newly born millisecond magnetars. Therefore, by considering the spin evolution…
