Towards an understanding of GRB prompt emission mechanism: I. The origin of spectral lags
Z. Lucas Uhm, Bing Zhang
Despite decades of investigations, the physical mechanism that powers the bright prompt -ray emission from gamma-ray bursts (GRBs) is still not identified. One important observa…
A Statistical Study of GRB X-ray Flares: Evidence of Ubiquitous Bulk Acceleration in the Emission Region
Lan-Wei Jia, Z. Lucas Uhm, Bing Zhang
When emission in a conical relativistic jet ceases abruptly (or decays sharply), the observed decay light curve is controlled by the high-latitude "curvature effect". Recently, Uhm…
Evidence of Bulk Acceleration of the GRB X-ray Flare Emission Region
Z. Lucas Uhm, Bing Zhang
Applying our recently-developed generalized version of the high-latitude emission theory to the observations of X-ray flares in gamma-ray bursts (GRBs), we present here clear obser…
Synchrotron Origin of the Typical GRB Band Function - A Case Study of GRB 130606B
Bin-Bin Zhang, Z. Lucas Uhm, Valerie Connaughton +2
We perform a time-resolved spectral analysis of GRB 130606B within the framework of a fast-cooling synchrotron radiation model with magnetic field strength in the emission region d…
