Correlations Between Lag, Luminosity, and Duration in Gamma-ray Burst Pulses
Jon Hakkila, Timothy W. Giblin, Jay P. Norris +2
We derive a new peak lag vs. peak luminosity relation in gamma-ray burst (GRB) pulses. We demonstrate conclusively that GRB spectral lags are pulse rather than burst properties and…
A Simple Two-Parameter Characterization of Gamma-Ray Burst Time Histories
Jon Hakkila, Timothy W. Giblin
A simple scheme delineates Long GRBs with similar time histories using the Internal Luminosity Function power-law index and the spectral lag. Several generalizations are made about…
Long-lag, Wide-Pulse Gamma-Ray Bursts
J. P. Norris, J. T. Bonnell, D. Kazanas +3
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…
Quiescent Burst Evidence for Two Distinct GRB Emission Components
Jon Hakkila, Timothy W. Giblin
We have identified two quiescent GRBs (bursts having two or more widely-separated distinct emission episodes) in which the post-quiescent emission exhibits distinctly different cha…
How Sample Completeness Affects Gamma-Ray Burst Classification
Jon Hakkila, Timothy W. Giblin, Richard J. Roiger +3
Unsupervised pattern recognition algorithms support the existence of three gamma-ray burst classes; Class I (long, large fluence bursts of intermediate spectral hardness), Class II…
Extended Power-Law Decays in BATSE Gamma-Ray Bursts: Signatures of External Shocks?
T. W. Giblin, V. Connaughton, J. van Paradijs +5
The connection between Gamma-Ray Bursts (GRBs) and their afterglows is currently not well understood. Afterglow models of synchrotron emission generated by external shocks in the G…
