A Review of Early-Time Optical Follow-ups with 2-m Robotic Telescopes
A. Gomboc, C. Guidorzi, C. G. Mundell +9
We summarise recent deep, rapid GRB follow-up observations using the RoboNet-1.0 network which comprises three fully-robotic 2-m telescopes, the Liverpool Telescope and the Faulkes…
Extensive multiband study of the X-ray rich GRB 050408. A likely off-axis event with an intense energy injection
A de Ugarte Postigo, T. A. Fatkhullin, G. Johannesson +40
Aims. Understand the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst. Methods. We present a multiband optical light curve, covering the…
REM observations of GRB 060418 and GRB 060607A: the onset of the afterglow and the initial fireball Lorentz factor determination
E. Molinari, S. D. Vergani, D. Malesani +32
Gamma-ray burst (GRB) emission is believed to originate in highly relativistic fireballs. Currently, only lower limits were securely set to the initial fireball Lorentz factor Gamm…
The circumburst environment of a FRED GRB: study of the prompt emission and X-ray/optical afterglow of GRB 051111
C. Guidorzi, A. Gomboc, S. Kobayashi +14
We report a multi-wavelength analysis of the prompt emission and early afterglow of GRB051111 and discuss its properties in the context of current fireball models. The detection of…
The early and late-time spectral and temporal evolution of GRB 050716
E. Rol, J. P. Osborne, K. L. Page +13
We report on a comprehensive set of observations of Gamma Ray Burst 050716, detected by the Swift satellite and subsequently followed-up rapidly in X-ray, optical and near infra-re…
The Remarkable Afterglow of GRB 061007: Implications for Optical Flashes and GRB Fireballs
C. G. Mundell, A. Melandri, C. Guidorzi +18
We present a multiwavelength analysis of Swift GRB 061007. The 2-m robotic Faulkes Telescope South (FTS) began observing 137 s after the onset of the gamma-ray emission, when the o…
Multi-wavelength afterglow observations of the high redshift GRB 050730
S. B. Pandey, A. J. Castro-Tirado, S. McBreen +22
GRB 050730 is a long duration high-redshift burst (z=3.967) discovered by Swift. The afterglow shows variability and is well monitored over a wide wavelength range. We present comp…
Anatomy of A Dark Burst - The Afterglow of GRB 060108
S. R. Oates, C. G. Mundell, S. Piranomonte +20
We report the first detection of an optical afterglow of a GRB (060108) that would have been classified as 'dark' in the absence of deep, rapid ground-based optical imaging with th…
High Quality Early Time Light Curves of GRB 060206: Implications for Gamma Ray Burst Environments and Energetics
A. Monfardini, S. Kobayashi, C. Guidorzi +8
The 2-m robotic Liverpool Telescope (LT) reacted promptly to the high-redshift (z=4.048) gamma-ray burst GRB 060206. The afterglow was identified automatically and multicolor r'i'z…
The variable X-ray light curve of GRB 050713A: the case of refreshed shocks
D. Guetta, F. Fiore, V. D'Elia +21
We present a detailed study of the spectral and temporal properties of the X-ray and optical emission of GRB050713a up to 0.5 day after the main GRB event. The X-ray light curve ex…
