Making a Short Gamma-Ray Burst from a Long one: Implications for the Nature of GRB 060614

Bing Zhang, Bin-Bin Zhang, En-Wei Liang +3

The absence of a supernova accompanying the nearby long GRB 060614 poses a great puzzle about the progenitor of this event and challenges the current GRB classification scheme. Thi…

A comprehensive analysis of Swift/XRT data: I. Apparent spectral evolution of GRB X-ray tails

Bin-Bin Zhang, En-Wei Liang, Bing Zhang

An early steep decay component following the prompt GRBs is commonly observed in {\em Swift} XRT light curves, which is regarded as the tail emission of the prompt gamma-rays. Prom…

Temporal Profiles and Spectral Lags of XRF 060218

En-Wei Liang, Bin-Bin Zhang, Mike Stamatikos +5

The spectral and temporal properties of the non-thermal emission ofthe nearby XRF 060218 in 0.3-150 keV band are studied. We show that both the spectral energy distribution and the…

GRB Radiative Efficiencies Derived from the Swift Data: GRBs vs. XRFs, Long vs. Short

Bing Zhang, Enwei Liang, Kim L. Page +17

We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by {\em Swift} before September 2005, and estimate the GRB radiative effi…

Inferring the emission regions for different kinds of gamma-ray bursts

Zhibin Zhang, G. Z. Xie, J. G. Deng +1

Using a theoretical model describing pulse shapes, we have clarified the relations between the observed pulses and their corresponding timescales, such as the angular spreading tim…

Revisiting the characteristics of the spectral lags in short gamma-ray bursts

Zhibin Zhang, G. Z. Xie, J. G. Deng +1

In this paper, we restudy the spectral lag features of short bright gamma-ray bursts (T90 < 2.6s) with a BATSE time-tagged event (TTE) sample including 65 single pulse bursts. We a…
