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…

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…

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…

Swift captures the spectrally evolving prompt emission of GRB 070616

R. L. C. Starling, P. T. O'Brien, R. Willingale +14

The origins of Gamma-ray Burst prompt emission are currently not well understood and in this context long, well-observed events are particularly important to study. We present the…

The First Swift BAT Gamma-Ray Burst Catalog

T. Sakamoto, S. D. Barthelmy, L. Barbier +13

We present the first Swift Burst Alert Telescope (BAT) catalog of gamma-ray bursts (GRBs), which contains bursts detected by the BAT between 2004 December 19 and 2007 June 16. This…
