Spectral Lags and the Lag-Luminosity Relation: An Investigation with Swift BAT Gamma-ray Bursts
T. N. Ukwatta, M. Stamatikos, K. S. Dhuga +7
Spectral lag, the time difference between the arrival of high-energy and low-energy photons, is a common feature in Gamma-ray Bursts (GRBs). Norris et al. 2000 reported a correlati…
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…
Spectral Lags of Gamma-Ray Bursts from Primordial Black Hole (PBH) Evaporations
T. N. Ukwatta, J. H. MacGibbon, W. C. Parke +5
Primordial Black Holes (PBHs), which may have been created in the early Universe, are predicted to be detectable by their Hawking radiation. PBHs with an initial mass of 5.0 * 10^1…
