Gamma-Ray Burst Pulses and Lateral Jet Motion
Jon Hakkila, Geoffrey N. Pendleton, Robert D. Preece +1
We propose that gamma-ray burst pulses are produced when highly-relativistic jets sweep across an observer's line-of-sight. We hypothesize that axisymmetric jet profiles, coupled w…
How Temporal Symmetry Defines Morphology in BATSE Gamma-Ray Burst Pulse Light Curves
Jon Hakkila
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 stru…
Time-Reversed Gamma-Ray Burst Light Curve Characteristics as Transitions between Subluminal and Superluminal Motion
Jon Hakkila, Robert Nemiroff
We introduce a simple model to explain the time-reversed and stretched residuals in gamma-ray burst (GRB) pulse light curves. In this model an impactor wave in an expanding GRB jet…
How Pulses in Short Gamma-Ray Bursts Constrain HMXRB Evolution
Jon Hakkila, Robert D. Preece
We demonstrate how pulse structures in Short gamma-ray bursts (SGRBs), coupled with observations of GRB/GW 170817A, constrain the geometries of dying HMXRB systems composed of merg…
Multidimensional analysis of Fermi GBM gamma-ray bursts
I. Horvath, J. Hakkila, Z. Bagoly +4
The Fermi GBM catalog provides a large database with many measured variables that can be used to explore and verify gamma-ray burst classification results. We have used Principal C…
Astro2020 Science White Paper: The Next Decade of Astroinformatics and Astrostatistics
A. Siemiginowska, G. Eadie, I. Czekala +49
Over the past century, major advances in astronomy and astrophysics have been largely driven by improvements in instrumentation and data collection. With the amassing of high quali…
