Gamma-Ray Bursts: Temporal Scales and the Bulk Lorentz Factor
E. Sonbas, G. A. MacLachlan, K. S. Dhuga +3
For a sample of Swift and Fermi GRBs, we show that the minimum variability timescale and the spectral lag of the prompt emission is related to the bulk Lorentz factor in a complex…
X - Ray Flares and Their Connection With Prompt Emission in GRBs
E. Sonbas, G. A. MacLachlan, A. Shenoy +2
We use a wavelet technique to investigate the time variations in the light curves from a sample of GRBs detected by Fermi and Swift. We focus primarily on the behavior of the flari…
Probing Curvature Effects in the Fermi GRB 110920
A. Shenoy, E. Sonbas, C. Dermer +7
Curvature effects in Gamma-ray bursts (GRBs) have long been a source of considerable interest. In a collimated relativistic GRB jet, photons that are off-axis relative to the obser…
A New Correlation Between GRB X-Ray Flares And The Prompt Emission
E. Sonbas, G. A. MacLachlan, A. Shenoy +2
From a sample of GRBs detected by the and missions, we have extracted the minimum variability time scales for temporal structures in the light curves associated wit…
The Hurst Exponent of Fermi GRBs
Glen MacLachlan, Ashwin Shenoy, Eda Sonbas +5
Using a wavelet decomposition technique, we have extracted the Hurst exponent for a sample of 46 long and 22 short Gamma-ray bursts (GRBs) detected by the Gamma-ray Burst Monitor (…
Infrahumps detected in Kepler light curve of V1504 Cygni
Robert Coyne, Ashwin Shenoy, Glen MacLachlan +6
We present a power spectral density analysis of the short cadence Kepler data for the cataclysmic variable V1504 Cygni. We identify three distinct periods: the orbital period (1.66…
The Minimum Variability Time Scale and its Relation to Pulse Profiles of Fermi GRBs
G. A. MacLachlan, A. Shenoy, E. Sonbas +4
We present a direct link between the minimum variability time scales extracted through a wavelet decomposition and the rise times of the shortest pulses extracted via fits of 34 Fe…
Minimum Variability Time Scales of Long and Short GRBs
G. A. MacLachlan, A. Shenoy, E. Sonbas +7
We have investigated the time variations in the light curves from a sample of long and short Fermi/GBM Gamma ray bursts (GRBs) using an impartial wavelet analysis. The results indi…
A New Frequency-Luminosity Relation for Long GRBs?
T. N. Ukwatta, K. S. Dhuga, D. C. Morris +7
We have studied power density spectra (PDS) of 206 long Gamma-Ray Bursts (GRBs). We fitted the PDS with a simple power-law and extracted the exponent of the power-law (alpha) and t…
