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 spectral evolution already seen in other gamma-ray bursts. The optical afterglow shows a shallow decay up to similar to 2 days after the burst, which is not consistent with standard afterglow models. The most intriguing feature is a very steep decay in the X-ray flux at similar to 2 x 10(4) s… Expand

The late peaking afterglow of GRB 100418A
GRB 100418A is a long gamma-ray burst (GRB) at redshift z = 0.6235 discovered with the Swift Gamma-ray Burst Explorer with unusual optical and X-ray light curves. After an initial short-lived, rapid… Expand
The prompt-afterglow connection in gamma-ray bursts: a comprehensive statistical analysis of Swift X-ray light curves
We present a comprehensive statistical analysis of Swift X-ray light-curves of GammaRay Bursts (GRBs) collecting data from more than 650 GRBs discovered by Swift and other facilities. The… Expand
Swift captures the spectrally evolving prompt emission of GRB 070616
The origins of gamma-ray burst (GRB) prompt emission are currently not well understood and in this context long, well-observed events are particularly important to study. We present the case of GRB… Expand
Towards the properties of long gamma-ray burst progenitors with Swift data
We investigate the properties of both the prompt and X-ray afterglows of gamma-ray bursts (GRBs) in the burst frame with a sample of 33 Swift GRBs. Assuming that the steep decay segment in the… Expand
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 to… Expand
The unusual X-ray emission of the short Swift GRB 090515: evidence for the formation of a magnetar?
The majority of short gamma-ray bursts (SGRBs) are thought to originate from the merger of compact binary systems collapsing directly to form a black hole. However, it has been proposed that both… Expand
Magnetar powered GRBs: explaining the extended emission and X-ray plateau of short GRB light curves
Extended emission (EE) is a high-energy, early time rebrightening sometimes seen in the light curves of short gamma-ray bursts (GRBs). We present the first contiguous fits to the EE tail and the… Expand
The Central Engine of GRB 130831A and the Energy Breakdown of a Relativistic Explosion
Gamma-ray bursts (GRBs) are the most luminous explosions in the Universe, yet the nature and physical properties of their energy sources are far from understood. Very important clues, however, can be… Expand
The swift x-ray telescope: status and performance
We present science highlights and performance from the Swift X-ray Telescope (XRT), which was launched on November 20, 2004. The XRT covers the 0.2-10 keV band, and spends most of its time observing… Expand
The unusual X-ray light-curve of GRB 080307: the onset of the afterglow?
TLDR
Using a two-component power-law-to-exponential model, the rising emission can be modelled as the onset of the afterglow, something which is very rarely seen in Swift-X-ray light curves. Expand

Swift multi-wavelength observations of the bright flaring burst GRB 051117A
TLDR
The superb quality of the early X-ray light-curve and spectra of this source, one of the brightest seen by the X-rays Telescope at such early times, allows an unprecedented look at the spectral and temporal evolution of the prompt and early afterglow emission for this GRB and allows us to place stringent limits on the detection of lines.

Panchromatic study of GRB 060124: From precursor to afterglow

The Early X-Ray Emission from GRBs
TLDR
Observations of the early X-ray emission for a sample of 40 gamma-ray bursts obtained using the Swift satellite, for which the narrow-field instruments were pointed at the burst within 10 minutes of the trigger, show that theX-ray light curve can be well described by an exponential that relaxes into a power law.

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 has… Expand
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
An unexpectedly rapid decline in the X-ray afterglow emission of long γ-ray bursts
‘Long’ γ-ray bursts (GRBs) are commonly accepted to originate in the explosion of particularly massive stars, which give rise to highly relativistic jets. Inhomogeneities in the expanding flow result… Expand
Evidence for a canonical gamma-ray burst afterglow light curve in the Swift XRT data

TLDR
The Swift Gamma-Ray Burst Explorer performed its first autonomous, X-ray follow-up to a newly detected GRB on 2005 January 17, within 193 s of the burst trigger by the Swift Burst Alert Telescope, and no optical afterglow could be confirmed. Expand
