Observation of GRB 221009A early afterglow in X/-ray energy band
Chao Zheng, Yan-Qiu Zhang, Shao-Lin Xiong +45
The early afterglow of a Gamma-ray burst (GRB) can provide critical information on the jet and progenitor of the GRB. The extreme brightness of GRB 221009A allows us to probe its e…
Modeling the Multi-band Afterglow of GRB 060908 with the Double Power-Law Hard Electron Energy Spectrum Model
Q. Zhang, S. L. Xiong, L. M. Song
Electrons accelerated in relativistic collisionless shocks are usually assumed to follow a power-law energy distribution with an index of . Observationally, although most gamma-…
Modeling the Multi-band Afterglows of GRB 060614 and GRB 060908: Further Evidence for a Double Power-Law Hard Electron Energy Spectrum
Q. Zhang, S. L. Xiong, L. M. Song
Electrons accelerated in relativistic collisionless shocks are usually assumed to follow a power-law energy distribution with an index of . Observationally, although most gamma-…
Late-Time Radio Re-Brightening of Gamma-Ray Burst Afterglows: Evidence for Double-Sided Jets
Zhuo Li, Li-Ming Song
The central engine of gamma-ray bursts (GRBs) is believed to eject double-sided ultra-relativistic jets. For an observed GRB, one of the twin jets should point toward us, and is re…
