GRB 080913 AT REDSHIFT 6.7
- J. Greiner, T. Krühler, K. Wiersema
- Physics
- 13 October 2008
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 the recognition of…
JET BREAKS AND ENERGETICS OF Swift GAMMA-RAY BURST X-RAY AFTERGLOWS
- J. Racusin, E. Liang, J. Osborne
- Physics
- 28 December 2008
We present a systematic temporal and spectral study of all Swift-X-ray Telescope observations of gamma-ray burst (GRB) afterglows discovered between 2005 January and 2007 December. After constructing…
Swift Observations of GRB 070110: An Extraordinary X-Ray Afterglow Powered by the Central Engine
- E. Troja, G. Cusumano, P. Schady
- Physics
- 8 February 2007
We present a detailed analysis of Swift multiwavelength observations of GRB 070110 and its remarkable afterglow. The early X-ray light curve, interpreted as the tail of the prompt emission, displays…
A Comprehensive Analysis of Swift XRT Data. II. Diverse Physical Origins of the Shallow Decay Segment
- E. Liang, Binbin Zhang, Bing Zhang
- Physics
- 10 May 2007
The origin of the shallow decay segment in Swift XRT light curves remains a puzzle. We analyze the properties of this segment with a sample of 53 long Swift GRBs detected before 2007 February. We…

Making a Short Gamma-Ray Burst from a Long One: Implications for the Nature of GRB 060614
- Bing Zhang, Binbin Zhang, E. Liang, N. Gehrels, D. Burrows, P. Mészáros
- Physics
- 8 December 2006
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. This burst displays a…
The masses of central supermassive black holes and the variability time-scales in gamma-ray loud blazars
The central supermassive black hole (SMBH) masses and variability time-scales of completed EGRET positive gamma-ray blazars loud were investigated. We generalized the Elliot-Shapiro relation to the…
A COMPREHENSIVE ANALYSIS OF FERMI GAMMA-RAY BURST DATA. I. SPECTRAL COMPONENTS AND THE POSSIBLE PHYSICAL ORIGINS OF LAT/GBM GRBs
- Binbin Zhang, Bing Zhang, Yun-Ming Dong
- Physics
- 17 September 2010
We present a systematic analysis of the spectral and temporal properties of 17 gamma-ray bursts (GRBs) codetected by the Gamma-ray Burst Monitor (GBM) and the Large Area Telescope (LAT) onboard the…
A Comprehensive Analysis of Swift XRT Data. III. Jet Break Candidates in X-Ray and Optical Afterglow Light Curves
- E. Liang, J. Racusin, Bing Zhang, Binbin Zhang, D. Burrows
- Physics
- 22 August 2007
The Swift XRT data for 179 GRBs (050124 to 070129) and the optical afterglow data for 57 pre- and post-Swift GRBs are analyzed to explore whether the observed breaks in the afterglow light curves can…
