Multi-wavelength Emission for a Post-merger Magnetar: The Magnetar-Driven Poynting Jet and Its Associated Pulsar Wind Nebula
Yun-Peng Li, Da-Bin Lin, Ning-Yuan Zhang +1
A newborn, rapidly rotating magnetar may form in a binary neutron star merger and drive a Poynting-flux-dominated relativistic jet. As the jet propagates outward, a forward shock (…
GRB 240825A: Early Reverse Shock and Its Physical Implications
Chao Wu, Yun Wang, Hua-Li Li +84
Early multiwavelength observations offer crucial insights into the nature of the relativistic jets responsible for gamma-ray bursts and their interaction with the surrounding mediu…
Radiation Spectrum of the Photospheric Emission for a Turbulent Relativistic Jet
Guo-Yu Li, Da-Bin Lin, Zhi-Lin Chen +1
The prompt -rays of gamma-ray bursts (GRBs) may originate from the photosphere of a relativistic jet. However, only a few GRBs have been observed with evident blackbody-like em…
Jet precession in gamma-ray bursts: The roles of fallback accretion and disk dynamics
Yun-Peng Li, Da-Bin Lin, Guo-Yu Li +1
The precession phenomenon of the jet in a gamma-ray burst (GRB) is a key probe of the physics of the central engine. Previous studies generally assumed a fixed precession period wh…
Variabilities of Gamma-ray Bursts from the Dynamics of Fallback Material after Tidal Disruption
Yun-Peng Li, Da-Bin Lin, Guo-Yu Li +2
The gamma-ray burst (GRB) GRB 211211A and GRB 060614, believed to originate from the merger of compact objects, exhibit similarities to the jetted tidal disruption event (TDE) Sw J…
Origin of TeV Emission in GRB 221009A: Co-effort of the External Reverse and Forward Shocks
Zhi-Lin Chen, Da-Bin Lin, Guo-Yu Li +1
The TeV emission detected in just five gamma-ray bursts (GRBs) is generally ascribed to the synchrotron emission or the synchrotron self-Compton process in the external forward sho…
