Discerning the physical origins of cosmological Gamma-ray bursts based on multiple observational criteria: the cases of z=6.7 GRB 080913, z=8.3 GRB 090423, and some short/hard GRBs
Bing Zhang, Bin-Bin Zhang, Francisco J. Virgili +10
(Abridged) The two high-redshift gamma-ray bursts, GRB 080913 at z=6.7 and GRB 090423 at z=8.3, recently detected by Swift appear as intrinsically short, hard GRBs. They could have…
Extended Emission of Short Gamma-Ray Bursts
Lin Lin, En-Wei Liang, Bin-Bin Zhang +1
Preliminary results of our analysis on the extended emission of short/medium duration GRBs observed with Swift/BAT are presented. The Bayesian blocks algorithm is used to analyze t…
Curvature Effect of a Non-Power-Law Spectrum and Spectral Evolution of GRB X-Ray Tails
Bin-Bin Zhang, Bing Zhang, En-Wei Liang +1
The apparent spectral evolution observed in the steep decay phase of many GRB early afterglows raises a great concern of the high-latitude "curvature effect" interpretation of this…
A Comprehensive Analysis of Swift/XRT Data: III. Jet Break Candidates in X-ray and Optical Afterglow Lightcurves
En-Wei Liang, Judith L. Racusin, Bing Zhang +2
The Swift/XRT data of 179 GRBs (from 050124 to 070129) and the optical afterglow data of 57 pre- and post-Swift GRBs are analyzed, in order to systematically investigate the jet-li…
A Comprehensive Analysis of the Swift/XRT Data: II. Diverse Physical Origins of the Shallow Decay Segment
En-Wei Liang, Bin-Bin Zhang, Bing Zhang
We analyze the properties of the shallow decay segment with a sample of 53 long Swift GRBs. We show that the distributions of its characteristics are log-normal or normal, and its…
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…
