Short-duration GRB 250221A Afterglow Driven by Two-Component Jets from the merger of a compact star
Xiao Tian, Hou-Jun Lü, Xiao-Xuan Liu +4
GRB 250221A is a short gamma-ray burst (GRB) at redshift , with a duration of 1.8 s and no extended emission in either Swift/Burst Alert Telescope or Konus-Wind bands. A r…
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…
Constraining the Cosmic-ray Energy Based on Observations of Nearby Galaxy Clusters by LHAASO
The LHAASO Collaboration, Zhen Cao, F. Aharonian +323
Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse -rays detectable by arrays such as L…
Evidence for the transition from thermal to non-thermal emission in the prompt emission of GRB 161117A
Xue-Zhao Chang, HouJun Lü, Jia-Ming Chen +1
GRB 161117A is a long-duration GRB with three main overlapping peaks. By analyzing the time-resolved spectra of its data observed with the Gamma-Ray Burst Monitor (GBM) on board th…
Probing the Nature of High-Redshift Long GRB 250114A and Its Magnetar Central Engine
Wen-Yuan Yu, Hou-Jun Lü, Xiao Tian +2
GRB 250114A is a long-duration gamma-ray burst (GRB) which triggered the Swift/BAT with a spectroscopic high-redshift at . The light curve of the prompt emission is comp…
The color evolution of magnetar-powered kilonova emission in merging neutron star-neutron star systems
Suo-Ning Wang, Hou-Jun Lü, Xiao-Xuan Liu +3
The first direct detection of the gravitational wave (GW) event GW170817 and its electromagnetic (EM) counterpart open a new window for studying of multi-messenger astronomy. Howev…
