Multiwavelength observations of GRB 110731A: GeV emission from onset to afterglow
LAT Collaboration, GBM Collaboration, Swift Collaboration +2
We report on the multiwavelength observations of the bright, long gamma-ray burst \GRB, by the \Fermi and \Swift observatories, and by the MOA and GROND optical telescopes. The ana…
A new low-B magnetar: Swift J1822.3-1606
A. Camero-Arranz, N. Rea, G. L. Israel +16
We report on the long term X-ray monitoring with Swift, RXTE, Suzaku, Chandra, and XMM-Newton of the outburst of the newly discovered magnetar Swift J1822.3-1606 (SGR 182-1606), fr…
GRB 091029: At the limit of the fireball scenario
R. Filgas, J. Greiner, P. Schady +20
Using high-quality, broad-band afterglow data for GRB 091029, we test the validity of the forward-shock model for gamma-ray burst afterglows. We used multi-wavelength (NIR to X-ray…
A correlation between intrinsic brightness and average decay rate of Swift UVOT GRB optical/UV light curves
S. R. Oates, M. J. Page, M. De Pasquale +5
We examine a sample of 48 Swift/UVOT long Gamma-ray Burst light curves and find a correlation between the logarithmic luminosity at 200s and average decay rate determined from 200s…
GRB100814A as a member of the growing set of bursts with sudden optical rebrightening
Massimiliano De Pasquale, N. P. Kuin, S. Oates +22
We present the gamma-ray, X-ray, optical and radio data for GRB100814A. At the end of the slow decline phase of the X-ray and optical afterglow, a sudden and prominent rebrightenin…
Multi-wavelength Observations of the Type IIb Supernova 2009mg
S. R. Oates, A. J. Bayless, M. D. Stritzinger +11
We present Swift UVOT and XRT observations, and visual wavelength spectroscopy of the Type IIb supernova (SN) 2009mg, discovered in the Sb galaxy ESO 121-G26. The observational pro…
