Constraining Circum-burst Environments of GRBs with Jet Break Features in X-ray Afterglows
Si-Ji Xin, Yu-Qi Zhou, Sheng-Jin Sun +6
The nature of the circum-burst medium serves as a key diagnostic for probing the progenitor systems and the physics of relativistic jet propagation in gamma-ray bursts (GRBs). In t…
Reconstruction of X-Ray Afterglow Light Curves of GRBs and its implication for constraining Cosmological Parameters
Yu-Qi Zhou, Shuang-Xi Yi, Yu-Peng Yang +4
Gamma-ray bursts (GRBs) serve as important cosmological probes, whose X-ray afterglow light curves (LCs) may exhibit a plateau phase (with temporal slope between 0 and 0.5) th…
Two Periodic Activity Epochs in FRB 20201124A: Coincident with Critical RM Evolution Epochs and Its Implications
Wen-Long Zhang, Chen-Ran Hu, Chen Du +12
Recent observations of the repeating fast radio burst FRB 20201124A by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) revealed a second-scale periodic modulation…
Constraining the initial Lorentz factor of gamma-ray bursts under different circumburst mediums
Sheng-Jin Sun, Shuang-Xi Yi, Yuan-Chuan Zou +4
The initial Lorentz factor () plays a crucial role in uncovering the physical characteristics of gamma-ray bursts (GRBs). Previous studies have indicated that the am…
Self-organized critical characteristics of teraelectronvolt photons from GRB 221009A
Wen-Long Zhang, Shuang-Xi Yi, Yuan-Chuan Zou +3
The very high-energy afterglow in GRB 221009A, known as the ``brightest of all time'' (BOAT), has been thoroughly analyzed in previous studies. In this paper, we conducted a statis…
Stable Case BB/BC Mass Transfer to Form GW190425-like Massive Binary Neutron Star Mergers
Ying Qin, Jin-Ping Zhu, Georges Meynet +14
On April 25th, 2019, the LIGO-Virgo Collaboration discovered a Gravitational-wave (GW) signal from a binary neutron star (BNS) merger, i.e., GW190425. Due to the inferred large tot…
