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…
Search for Point Sources of High Energy Neutrinos with Final Data from AMANDA-II
The IceCube Collaboration
We present a search for point sources of high energy neutrinos using 3.8 years of data recorded by AMANDA-II during 2000-2006. After reconstructing muon tracks and applying selecti…
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…
