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 Fermi Gamma-ray Burst Monitor (GBM) Gamma-Ray Burst (GRB) light curves comprised of 379 pulses. Pulses used in this study were fitted with lognormal functions, whereas the wavelet technique used employs a multiresolution analysis that does not rely on identifying distinct pulses. By applying a corrective filter to… Expand

Variability Time Scales of GRBs
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 and compared those results withExpand

Temporal Decomposition Studies of GRB Lightcurves
Gamma-ray bursts (GRB) are extremely energetic events and produce highly diverse light curves. Light curves are believed to be resulting from internal shocks reflecting the activities of the GRBExpand
Gamma-Ray Bursts: Temporal Scales and the Bulk Lorentz Factor
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 manner: For smallExpand
The Hurst exponent of Fermi gamma-ray bursts
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 (GBM) aboard theExpand
How Temporal Symmetry Defines Morphology in BATSE Gamma-Ray Burst Pulse Light Curves
We present compelling evidence that most gamma-ray burst (GRB) pulse light curves can be characterized by a smooth single-peaked component coupled with a more complex emission structure that isExpand
Fermi-LAT Observations of the Gamma-Ray Burst GRB 130427A
Temporal and spectral analyses of GRB 130427A challenge the widely accepted model that the nonthermal high-energy emission in the afterglow phase of GRBs is synchrotron emission radiated by electrons accelerated at an external shock. Expand
Distinguishing short and long $Fermi$ gamma-ray bursts
Two classes of gamma-ray bursts (GRBs), short and long, have been determined without any doubts, and are usually ascribed to different progenitors, yet these classes overlap for a variety ofExpand
Are short Gamma Ray Bursts similar to long ones
Abstract The apparent separation of short and long Gamma-Ray Bursts (GRBs) in the hardness ratio vs duration plot has been considered as a direct evidence of the difference between these twoExpand
On the limit between short and long GRBs
Two classes of GRBs have been identified thus far without doubt and are prescribed to different physical scenarios—NS-NS or NS-BH mergers, and collapse of massive stars, for short and long GRBs,Expand


Temporal properties of gamma-ray bursts as signatures of jets from the central engine
A comprehensive temporal analysis has been performed on the 319 brightest GRBs with T90 > 2s from the BATSE current catalog. The GRBs were denoised using wavelets and subjected to an automatic pulseExpand
Minimum variability time-scales of long and short GRBs
ABSTRACT We have investigated the variability of a sample of long and short Fermi/GBM Gammaray bursts (GRBs) using a fast wavelet technique to determine the smallest timescales. The results indicateExpand
Extension of an exponential light-curve gamma-ray burst pulse model across energy bands
A simple mathematical model of gamma-ray burst(GRB) pulses in time, suggested by Norris et al., is extended across energy. For a class of isolated pulses, two fit parameters appear to be effectivelyExpand
Temporal Deconvolution study of Long and Short Gamma-Ray Burst Light curves

Correlations between Lag, Duration, Peak Luminosity, Hardness, and Asymmetry in Long GRB Pulses
Continued study of the BATSE catalog verifies previously‐identified correlations between pulse lag and pulse duration and corresponding anti‐correlations between both properties and pulse peak fluxExpand

Long-Lag, Wide-Pulse Gamma-Ray Bursts
Currently, the best available probe of the early phase of gamma-ray burst (GRB) jet attributes is the prompt gamma-ray emission, in which several intrinsic and extrinsic variables determine GRB pulseExpand

The Pulse Scale Conjecture and the Case of BATSE Trigger 2193
The pulses that compose gamma-ray bursts (GRBs) are hypothesized to have the same shape at all energies, differing only by scale factors in time and amplitude. This "pulse scale conjecture" isExpand

Gamma-ray bursts are the most luminous explosions in the Universe, and their origin as well as mechanism are the focus of intense research and debate. More than three decades since theirExpand
