Jet breaks and Energetics of Swift GRB X-ray Afterglows
J. L. Racusin, E. W. Liang, D. N. Burrows +6
We present a systematic temporal and spectral study of all Swift-XRT observations of GRB afterglows discovered between 2005 January and 2007 December. After constructing and fittin…
X-Ray Flares of Gamma-Ray Bursts: Quakes of Solid Quark Stars?
Renxin Xu, Enwei Liang
We propose a star-quake model to understand X-ray flares of both long and short Gamma-ray bursts (GRBs) in a solid quark star regime. Two kinds of central engines for GRBs are avai…
GRB 080913 at redshift 6.7
J. Greiner, T. Kruehler, J. P. U. Fynbo +44
We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND which led to the discovery of its optical/NIR afterglow and…
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…
Swift X-ray Afterglows and the Missing Jet Break Problem
J. L. Racusin, E. -W. Liang, D. N. Burrows +3
We present a systematic survey of the temporal and spectral properties of all GRB X-ray afterglows observed by Swift-XRT between January 2005 and July 2007. We have constructed a c…
Thermal Emission from a Hot Cocoon Surrounding the Jet of XRF 060218
Enwei Liang, Bing Zhang, Bin-Bin Zhang +1
It is long speculated that long duration gamma-ray bursts (GRBs) originate froma relativistic jet emerging from a collapsing massive star progenitor. Although associations of core-…
