Epeak estimator for Gamma-Ray Bursts Observed by the Swift Burst Alert Telescope
T. Sakamoto, G. Sato, L. Barbier +13
We report a correlation based on a spectral simulation study of the prompt emission spectra of gamma-ray bursts (GRBs) detected by the Swift Burst Alert Telescope (BAT). The correl…
Correlative Spectral Analysis of Gamma-Ray Bursts using Swift-BAT and GLAST-GBM
Michael Stamatikos, Takanori Sakamoto, David L. Band
We discuss the preliminary results of spectral analysis simulations involving anticipated correlated multi-wavelength observations of gamma-ray bursts (GRBs) using Swift's Burst Al…
A Correlation of Spectral Lag Evolution with Prompt Optical Emission in GRBs?
Michael Stamatikos, Tilan N. Ukwatta, Takanori Sakamoto +1
We report on observations of correlated behavior between the prompt gamma-ray and optical emission from GRB 080319B, which (i) strongly suggest that they occurred within the same a…
The 2008 May burst activation of SGR 1627-41
P. Esposito, G. L. Israel, S. Zane +16
In May 2008 the soft gamma-ray repeater SGR 1627-41 resumed its bursting activity after nearly a decade of quiescence. After detection of a bright burst, Swift pointed its X-ray te…
The Swift Discovery of X-ray Afterglows Accompanying Short Bursts from SGR 1900+14
Y. E. Nakagawa, T. Sakamoto, G. Sato +3
The discovery of X-ray afterglows accompanying two short bursts from SGR 1900+14 is presented. The afterglow luminosities at the end of each observation are lower by 30-50% than th…
Screening High-z GRBs with BAT Prompt Emission Properties
T. N. Ukwatta, T. Sakamoto, M. Stamatikos +2
Detecting high-z GRBs is important for constraining the GRB formation rate, and tracing the history of re-ionization and metallicity of the universe. Based on the current sample of…
Multiple Component Analysis of Time Resolved Spectra of GRB041006: A Clue to the Nature of Underlying Soft Component of GRBs
Yuji Shirasaki, Atsumasa Yoshida, Nobuyuki Kawai +30
GRB 041006 was detected by HETE-2 at 12:18:08 UT on 06 October 2004. This GRB displays a soft X-ray emission, a precursor before the onset of the main event, and also a soft X-ray…
Spectral Properties of Prompt Emission of Four Short Gamma-Ray Bursts Observed by the Suzaku-WAM and the Konus-Wind
Masanori Ohno, Yasushi Fukazawa, Takuya Takahashi +16
We have performed a joint analysis of prompt emission from four bright short gamma-ray bursts (GRBs) with the Suzaku-WAM and the Konus-Wind experiments. This joint analysis allows…
