Variability in the Prompt Emission of Swift-BAT Gamma-Ray Bursts
T. N. Ukwatta, K. S. Dhuga, W. C. Parke +8
We present the results of our study of the variability time scales of a sample of 27 long Swift Gamma-Ray Bursts (GRBs) with known redshifts. The variability time scale can help ou…
The Correlation of Spectral Lag Evolution with Prompt Optical Emission in GRB 080319B
Michael Stamatikos, Tilan N. Ukwatta, Takanori Sakamoto +8
We report on observations of correlated behavior between the prompt gamma-ray and optical emission from GRB 080319B, which confirm that (i) they occurred within the same astrophysi…
Investigating the Possibility of Screening High-z GRBs based on BAT Prompt Emission Properties
T. N. Ukwatta, T. Sakamoto, K. S. Dhuga +5
Being able to quickly select among gamma-ray bursts (GRBs) seen by the Swift satellite those which are high-z candidates would give ground-based observers a better chance to determ…
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…
