We report the results of the Chandra observations of the Swift-discovered short gamma-ray burst GRB 050724. Chandra observed this burst twice, about 2 days after the burst and a second time 3 weeks later. The first Chandra pointing occurred at the end of a strong late-time flare. About 150 photons were detected during this 49.3 ks observation in the 0.4-10.0 keV range. The spectral fit is in good agreement with spectral analysis of earlier Swift XRT data. In the second Chandra pointing the… Expand

LATE-TIME DETECTIONS OF THE X-RAY AFTERGLOW OF GRB 060729 WITH CHANDRA—THE LATEST DETECTIONS EVER OF AN X-RAY AFTERGLOW
We report on five Chandra observations of the X-ray afterglow of the gamma-ray burst (GRB) 060729 performed between 2007 March and 2008 May. In all five observations, the afterglow is clearlyExpand
SWIFT and XMM-Newton observations of the extraordinary gamma-ray burst 060729: More than 125 days of X-ray afterglow
TLDR
The afterglow of this burst was exceptionally bright in X-rays as well as at UV/optical wavelengths, showing an unusually long slow decay phase, suggesting a larger energy injection phase at early times than in other bursts. Expand
Swift observations of GRB 060614: an anomalous burst with a well behaved afterglow
TLDR
Spectral analysis of the Swift observations of GRB 060614 shows that the burst presents standard optical, ultraviolet and X-ray afterglows, detected beginning 4 ks after the trigger, and that the peak energy of the burst has decreased to as low as 8 keV at the beginning of the XRT observation.

An achromatic break in the afterglow of the short GRB 140903A: evidence for a narrow jet
We report the results of our observing campaign on GRB140903A, a nearby (z=0.351) short duration (T90~0.3 s) gamma-ray burst discovered by Swift. We monitored the X-ray afterglow with Chandra up toExpand
SHORT GRB 130603B: DISCOVERY OF A JET BREAK IN THE OPTICAL AND RADIO AFTERGLOWS, AND A MYSTERIOUS LATE-TIME X-RAY EXCESS
We present radio, optical/NIR, and X-ray observations of the afterglow of the short-duration Swift and Konus-Wind GRB 130603B, and uncover a break in the radio and optical bands at ≈0.5 day after theExpand
Gamma-ray burst jet breaks revisited
Gamma-ray Burst (GRB) collimation has been inferred with the observations of achromatic steepening in GRB light curves, known as jet breaks. Identifying a jet break from a GRB afterglow lightcurveExpand
A Jet Break in the X-Ray Light Curve of Short Grb 111020a: Implications for Energetics and Rates
We present broadband observations of the afterglow and environment of the short GRB 111020A. An extensive X-ray light curve from Swift/XRT, XMM-Newton, and Chandra, spanning {approx}100 s to 10 daysExpand
Jet Breaks and Energetics of Swift Gamma-Ray Burst X-Ray Afterglows
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 constructingExpand

TLDR
A complete accounting of Swift-era short-burst localizations and proposed host galaxies is made, and the implications of these observations for the distances, energetics and environments of short bursts and the nature of their progenitors are discussed. Expand
Multi-color observations of short GRB afterglows: 20 events observed between 2007 and 2010
We report on follow-up observations of 20 short-duration gamma-ray bursts (GRBs; T90 < 2 s) performed in grizJHKs with the Gamma-Ray Burst Optical Near-Infrared Detector (GROND) between mid-2007 andExpand

The swift X-ray flaring afterglow of GRB 050607
TLDR
Observations of GRB 050607, the fourth case of a GRB discovered by Swift with flares superimposed on the overall fading X-ray afterglow, are presented, showing a very steep rise and a shallower decay similar to the fast rise, exponential decay that are frequently observed in the gamma-ray prompt emission.

The X-ray afterglow of the short gamma ray burst 050724
Received; accepted Abstract. Short duration ( < ∼ 2 s) Gamma-ray bursts (GRBs) have been a mystery since their discovery. Until May 2005 very little was known about short GRBs, but this situation hasExpand
The giant X-ray flare of GRB 050502B: Evidence for late-time internal engine activity
TLDR
The evidence presented below, including spectral and, particularly, timing information during and around the giant flare, suggests that this giant flare was the result of internal dissipation of energy due to late central engine activity, rather than an afterglow-related effect. Expand
Discovery of an X-ray afterglow associated with the γ-ray burst of 28 February 1997
Establishing the nature of γ-ray bursts is one of the greatest challenges in high-energy astrophysics. The distribution of these bursts is isotropic across the sky, but inhomogeneous in space, with aExpand
Evidence for a canonical gamma-ray burst afterglow light curve in the Swift XRT data
We present new observations of the early X-ray afterglows of the first 27 gamma-ray bursts (GRBs) well observed by the Swift X-Ray Telescope (XRT). The early X-ray afterglows show a canonicalExpand
The afterglow of GRB 050709 and the nature of the short-hard γ-ray bursts
The final chapter in the long-standing mystery of the γ-ray bursts (GRBs) centres on the origin of the short-hard class of bursts, which are suspected on theoretical grounds to result from theExpand
Discovery of the short γ-ray burst GRB 050709
Gamma-ray bursts (GRBs) fall into two classes: short-hard and long-soft bursts. The latter are now known to have X-ray and optical afterglows, to occur at cosmological distances in star-formingExpand
The Dynamics and Light Curves of Beamed Gamma-Ray Burst Afterglows
The energy requirements of gamma-ray bursts have in past been poorly constrained because of three major uncertainties: the distances to bursts, the degree of burst beaming, and the efficiency ofExpand
