Observations of GX 339-4 in 1996
I. A. Smith, E. P. Liang, D. Lin +9
GX 339-4 is an unusual black hole candidate in that it is a persistent source, being detected by X-ray telescopes most of the time, but it also has nova-like flaring states. In 199…

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…

Time-dependent photoelectric absorption, photoionization and fluorescence line emission in gamma-ray burst environments
M. Boettcher, C. D. Dermer, A. W. Crider +1
If gamma-ray bursts are associated with dense star-forming regions in young galaxies, photoelectric absorption by the dense circumburster material (CBM) will occur. As the burst ev…
