Diverse Morphologies of GRB X-Ray Plateaus within a Common Magnetar Framework
Xiao-Fei Dong, Yong-Feng Huang, Nurimangul Nurmamat +7
The origin of the X-ray plateau phase in gamma-ray bursts (GRBs) remains an open problem. In particular, it is unclear whether GRBs with different temporal morphologies (i.e., with…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
A second-scale periodicity in an active repeating fast radio burst source
Chen Du, Yong-Feng Huang, Jin-Jun Geng +14
Fast radio bursts (FRBs) are fierce radio flashes from the deep sky. Abundant observations have indicated that highly magnetized neutron stars might be involved in these energetic…
Gamma-Ray Bursts: Evidence for a Common Origin of X-ray Plateaus with Diverse Temporal Decay Index
Xiao-Fei Dong, Yong-Feng Huang, Chen Deng +8
A significant fraction of gamma-ray bursts (GRBs) exhibit a plateau in the early X-ray afterglow light curve, whose mechanism remains uncertain. While the post-plateau normal decay…
Constraining the Supernova Remnant Environment of FRB 190520B with Dispersion Measure and Scattering Timescale
Jia-Peng Wei, Chen Deng, Gwenael Giacinti +4
FRB 190520B is a repeating fast radio burst source whose large dispersion measure (DM) and temporal broadening suggest a dense and evolving local environment. In this work, we test…
Discovery of a radio jet in the Cloverleaf Quasar at z = 2.56
Lei Zhang, Zhi-Yu Zhang, James. W. Nightingale +10
The fast growth of supermassive black holes and their feedback to the host galaxies play an important role in regulating the evolution of galaxies, especially in the early Universe…
