A Non-Triggered Burst Supplement to the BATSE Gamma-Ray Burst Catalogs
J. M. Kommers, W. H. G. Lewin, C. Kouveliotou +4
The Burst and Transient Source Experiment (BATSE) on the Compton Gamma Ray Observatory detected gamma-ray bursts (GRBs) with a real-time burst detection (or "trigger") system runni…
The Role of the BATSE Instrument Response in Creating the Gamma-Ray Burst E-Peak Distribution
J. J. Brainerd, G. Pendleton, R. Mallozzi +2
All gamma-ray bursts are observed to have approximately the same characteristic gamma-ray energy. We show in this article that for bursts in the BATSE data set, this property as me…
Spectral Hardness Decay with Respect to Fluence in BATSE Gamma-Ray Bursts
A. Crider, E. P. Liang, R. D. Preece +5
We have analyzed the evolution of the spectral hardness parameter Epk as a function of fluence in gamma-ray bursts. We fit 41 pulses within 26 bursts with the trend reported by Lia…
Evolution of the Low-Energy Photon Spectra in Gamma-Ray Bursts
A. Crider, E. P. Liang, I. A. Smith +6
We report evidence that the asymptotic low-energy power law slope alpha (below the spectral break) of BATSE gamma-ray burst photon spectra evolves with time rather than remaining c…
