Swift-UVOT captures the earliest ultraviolet spectrum of a Gamma Ray Burst
N. P. M. Kuin, W. B. Landsman, M. J. Page +22
We present the earliest ever ultraviolet spectrum of a gamma-ray burst (GRB) as observed with the Swift-UVOT. The GRB 081203A spectrum was observed for 50 seconds with the UV grism…
Testing the blast wave model with Swift GRBs
P. A. Curran, R. L. C. Starling, A. J. van der Horst +1
The complex structure of the light curves of Swift GRBs has made the identification of breaks, and the interpretation of the blast wave caused by the burst, more difficult than in…
Constraining the energy budget of GRB 080721
R. L. C. Starling, E. Rol, A. J. van der Horst +17
We follow the bright, highly energetic afterglow of Swift-discovered GRB 080721 at z=2.591 out to 36 days or 3e6 s since the trigger in the optical and X-ray bands. We do not detec…
Late time observations of GRB080319B: jet break, host galaxy and accompanying supernova
Nial R. Tanvir, Evert Rol, Andrew Levan +15
The Swift discovered GRB080319B was by far the most distant source ever observed at naked eye brightness, reaching a peak apparent magnitude of 5.3 at a redshift of z=0.937. We pre…
Robust photometric redshift determinations of gamma-ray burst afterglows at z > 2
P. A. Curran, R. A. M. J. Wijers, M. H. M. Heemskerk +3
Theory suggests that about 10% of Swift-detected gamma-ray bursts (GRBs) will originate at redshifts greater than 5 yet a number of high redshift candidates may be left unconfirmed…
The Swift capture of a long X-ray burst from XTE J1701-407
Manuel Linares, Anna L. Watts, Rudy Wijnands +5
XTE J1701-407 is a new transient X-ray source discovered on June 8th, 2008. More than one month later it showed a rare type of thermonuclear explosion: a long type I X-ray burst. W…
Photometry and spectroscopy of GRB 060526: A detailed study of the afterglow and host galaxy of a z=3.2 gamma-ray burst
C. C. Thöne, D. A. Kann, G. Jóhannesson +58
Aims: With this paper we want to investigate the highly variable afterglow light curve and environment of gamma-ray burst (GRB) 060526 at . Methods: We present one of the…
GRB 080319B: A Naked-Eye Stellar Blast from the Distant Universe
J. L. Racusin, S. V. Karpov, M. Sokolowski +81
Long duration gamma-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation…
Multiwavelength analysis of the intriguing GRB 061126: the reverse shock scenario and magnetization
A. Gomboc, S. Kobayashi, C. Guidorzi +30
We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multi-color optical imaging from ten ground-based telescopes. G…
On the nature of late X-ray flares in Swift Gamma-ray Bursts
P. A. Curran, R. L. C. Starling, P. T. O'Brien +3
Previously detected in only a few gamma-ray bursts (GRBs), X-ray flares are now observed in ~50% of Swift GRBs, though their origins remain unclear. Most flares are seen early on i…
The hidden X-ray breaks in afterglow light curves
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers +1
Gamma-Ray Burst (GRB) afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX, or pre-Swift era. Specifically, relatively fe…
Are the missing X-ray breaks in Gamma-ray Burst afterglow light curves merely hidden?
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX, or pre-Swift era. Specifically, relatively few brea…
The host of GRB 060206: kinematics of a distant galaxy

P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers +20
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX era. We present our multi-wavelength analysis of GRB…
